Celsius



The Celsius is the party's primary airship in Final Fantasy X-2 and the mobile base of operations for the Gullwings. The party's missions begin and end onboard the ship. The ship uses a sphere wave detector to detect waves emitted by spheres.

The facilities on the airship include a number of resources from Shinra including a bestiary, information about Spira, and a sphere theater. A shop and inn, and a number of refilling treasure chests are also available. As the game progresses many of the airship's passengers will also offer their services to compliment the airship's; these include an additional shop and the ability to capture and store chocobos.

Final Fantasy X-2
One of the few airships in current operation around Spira, the Celsius was unearthed in the cold north by the Al Bhed faction some time during the two year gap between Final Fantasy X and Final Fantasy X-2. Presumably the airship was originally created some 1,000 years before game events; before Sin and the oppression of machina.

In order to recover the Celsius when forming a sphere hunting organization, Brother and Buddy traveled to the north. At first, their attempt to find the airship appeared to be failing, but then they spotted a single gull in the sky and decided to follow it. The gull led them to the airship, and so, based on this event, the group was named the Gullwings, after the bird.

Brother and Buddy piloted the airship with Rikku and Shinra as crew, after breaking away from Cid. They were joined by Paine, who wished to fly aboard the airship in return for her offering her combat skills. When Yuna also joins the group, wishing to find the truth behind a sphere, which showed a man resembling Tidus, Kimahri had found, the "YRP" (the first initials of Yuna, Rikku, and Paine) task group was formed.

The sphere wave detector detects sphere waves at the top of Mt. Gagazet's Floating Ruins. They aim to drop the main party at the top of the ruins but end up dropping them off not-so close. The party obtain the sphere and return it to the Celsius but it is no use to the party. Following this sphere waves are detected in Besaid and in Zanarkand Ruins. In Besaid the party find another dud in the cave, while in Zanarkand Ruins they find a broken sphere. Later the Gullwings receive reports of an awesome sphere in Kilika Woods which they steal from New Yevon.

The sphere showed the man seen in the earlier sphere in front of a massive machina. After this the crew of the airship decide to make Yuna dance. A band that Brother picked up earlier is used during the event on the bridge of the ship.

The Gullwings decide to give the sphere they just stole to the Youth League (or New Yevon if the player chooses). During this time the Leblanc Syndicate boards the Celsius and steals a sphere. A distress signal from Barkeep alerts the crew and they eventually discover the broken Zanarkand Ruins sphere was stolen, in exchange for a sphere containing a message from the syndicate showing the act.

The Gullwings steal Leblanc Syndicate uniforms and break into Chateau Leblanc where the syndicate have assembled the broken sphere with the other half of the sphere they have and bring the reassemble sphere back to the airship. The Gullwings join forces with the Leblanc Syndicate and they bring them back to the airship so the team can head to Bevelle after discovering the reassembled sphere of the machina was recorded beneath Bevelle.

After the events of Bevelle the team are called up to the airship after fiends come from the temples. The Gullwings decide to make it their mission to dispatch their fiends. After they accomplish this, Shinra shows them his new invention called CommSpheres.

With CommSpheres, a technology developed by Shinra, Yuna contacts people from all areas of Spira from the airship. Yuna receives updates from various characters through this. Later the system is used to advertise a concert starring Yuna held in an attempt to unite the denizens of Spira. With help from Tobli and his associates many people gather for the concert in the Thunder Plains. The exposed deck of the Celsius serves as a stage for Yuna's performance.

After the performance the Gullwings decide to go to the Farplane to find Shuyin. They enter through one of the holes that lead down there.

Final Fantasy X-2: Last Mission
The Celsius is operated by only Yuna, Rikku, and Paine during their adventure in the Iutycyr Tower.

Boarding and parting
When on the airship, the player can leave by talking to Buddy. Doing so will open up a menu which lists all the available locations. Highlighting over a specific location on the list will update a text box in the bottom-right of the screen which will potentially give details on missions and events available in that specific area. Not all events are mentioned here however.

Areas will be flagged as "Hotspots" if there are events related to story progression there. In Chapter 5 areas will be flagged as hotspots if the player can do any missions in the specific location. At certain points in the game (usually after all Hotspot-related missions are complete) the player will be forced to go to one specific location and not be able to choose from the list.

The player can board the Celsius at Save Spheres throughout Spira from the Save menu. This will teleport the player to the bridge of the airship. A number of scenarios will have this option omitted. The Save Sphere found on the airship will not have this option since the player will already be on the airship at this point. Also during scenarios where the player is forced to go to a specific location, such as the events of Kilika at the end of Chapter 1, the player will not be able to return to the airship thereafter until the mission is complete.

The player will also often board the airship after the completion of a mission. This means that the player will have to return to the area to see repercussions from the mission, to see updated reactions from non-player characters, and in some cases to receive items from said characters. In this scenario a skippable establishing shot of the Celsius occurs before Yuna emerges from the elevator out onto the bridge.

Like in Final Fantasy X, the player does not need the airship to travel to most areas as most of it is one land mass. This means the player can travel from Luca to Macalania, and from Macalania to Zanarkand Ruins without the need for an airship. Boats will not take the player to the isles of Besaid or Kilika, and Bikanel can only be accessed through the airship too.

Locations
The airship contains three floors plus an open-air deck, all accessed via a single elevator. When the player enters the elevator a diagram of the Celsius is given and a list of locations. Highlighting a location will have the diagram show where the area is located. In each area the other three locations will be listed, while the fourth option, "Cancel", will keep the player in the same place. The Deck is an exception and the elevator will always take the player down to the Bridge.

Deck
The airship's open-air top deck can be accessed by the elevator and is a favored spot by the party to unwind, think or simply to seek privacy. It doesn't matter if the airship is moving, one can still access and walk around the exposed deck with abandon.

The player must go to the Deck to speak to Paine at the start of Chapter 4, to be able to progress. Cid will appear here in Chapter 5, after he exits the New Cave for the Celsius. Due to this he will notably appear during the cutscene. Going up to the Deck will have him walk to the Bridge. Due to him appearing on the Deck when returning to the airship after Episode Complete he will be visible in the establishing shot of the airship.

Bridge
The bridge is the heart, brain and control hub of the ship. At the back of the area is the passage to the elevator. In this area is the airship's Save Sphere.

On the right of the area Shinra sits at a computer. Shinra can provide information about Spira, or give tutorials about game mechanics. Spheres found by the player can be viewed on the player in the Treasure Spheres option, enemies previously fought by the player can be reviewed in Shinra's Bestiary, information about characters can be found in Shinra's Dossiers, and tutorials and information about terms and events can be found in Shinra's Guide to Everything. During Chapter 4 and onward Shinra also allows the player to use CommSpheres to communicate with people in other areas of Spira, however the system plays no role beyond Chapter 4.

Rikku and Paine will share their thoughts about the area last visited or based on the mission previously done, and Brother will comment on various things as well. To travel around the world map the player must talk to Buddy, the navigator who resides in the seat at the front-left of the airship, and choose a destination.

Speaking with Brother at the start of Chapter 1 will score the player three Al Bhed Primer key items and an explanation of learning Al Bhed. Talking to Buddy at this time will score the player one Al Bhed Primer key item. These four key items change depending on the order and what Al Bhed Primers have already being earned, although assuming the player has none at this point the four will be the Al Bhed Primer XXI, Al Bhed Primer XIX, Al Bhed Primer III, and Al Bhed Primer XVII. At the start of Chapter 2, another Al Bhed Primer can be earned after the scene at the start of the chapter if the player has not already earned all the primers.

In Chapter 4, Tobli appears on the Bridge after viewing the crowd scene. Interacting with him here allows the player to continue the story and start the performance. After the performance Maechen appears on the Bridge and is used for a story-progressing scene.

If the circumstances for Cid boarding the airship are met, Cid will go to the Bridge after the player character finds him on the Deck. A scene of him in a dispute with Brother ensues, before he exits to the Engine Room where he resides thereafter.

Engine Room
The engines of the Celsius are housed in the engine room. Four treasure chests reside in the room that refill every new chapter.

When Leblanc is on-board the Celsius, she can be found here in chapter four, after the Thunder Plains concert. Cid resides here if the player recruits him to the airship and watches his scenes on the Deck and on the Bridge.

A set of stairs lead downward, however these do not lead to anything. It is implied to be the staircase down to the entrance and exit of the airship.

Cabin
In the cabin, Barkeep the Hypello runs the Gullstore, which is a basic shop, and will let Yuna sleep in one of the beds. While there is no real reason to have beds in the game considering Save Spheres fully heal the party, in each chapter sleeping in the bed will add to the percentage and be necessary for getting 100% in a single playthrough.

Occasionally, other passengers on the Celsius will wait here; O'aka XXIII will be waiting here to sell his wares if the Gullwings agree to hold him during Chapter 1, and Calli and Clasko can be found in the cabin if invited onboard the Celsius. Clasko will be found on top-floor the first time he is recruited on Chapter 1 and on the bottom the second time he can be recruited on Chapter 2.

At the start of Chapter 2 the band, Pukara, Borra, and Daraya, from Macalania Woods, can be found in the corridor here. They are part of the moving the band minigame. They will appear in the corridor until the end of Chapter 2.

Additionally, any chocobos caught using Shinra's ChocoPorter device in Chapter 4 will be found here.

In Chapter 5, Darling can appear in the Cabin if the scene with Brother and Barkeep are talking. This scene is unlocked after resting in the Cabin on every chapter.

When O'aka first opens his shop on the Celsius, he sells basic items at a slightly reduced price. If the player plays off his debts before Chapter 3 he starts selling those items at a drastically reduced price which is lower than the regular sell price.

The Gullstore
The Gullstore is run by Barkeep in the Cabin. The shop remains the same throughout the game with the only change occurring in Chapter 3 where he will start selling Hi-Potion items. O'aka sells all the same items, including the Hi-Potion despite appearing earlier than Chapter 3, and at an undercut price (98%). After O'aka's debts are paid, the undercut price is 10%, which is less than the Gullstore's sell price (the standard 25%).

O'aka's Shop
When O'aka is in debt his items will cost 98% of their base price. If O'aka has had his debts paid his items will cost 10% of their base price. The shop will stay available until the start of Chapter 3 when O'aka will leave the airship. If his debts are not paid off by Chapter 3, he will remain on the airship until his debts are paid.

It is only possible to buy from O'aka, it is not possible to sell to him.

Shinra's Guide to Everything
Shinra's Guide to Everything teaches the basics of the game and contains numerous tutorials.

Selecting the "Using Garment Grids" tutorial earns the player the Vanguard Garment Grid.

Shinra's Guide also contains a Glossary of Spira sub-menu. This glossary contains numerous terms from the game and information about them.

Treasure Spheres
Treasure Spheres is an option on the menu when interacting with Shinra. The option allows the player to view what is filmed on spheres they have in their possession. The movies do not use the same name as the key item. Many of the spheres are earned through the story, however a number of others are optional and primarily focus to expand the story of the game.

Most optional treasure spheres can be permanently missed. One sphere, the Gippal Sphere, is only earned in a scenario where they will not get Episode Complete, only Episode Concluded in a scenario, namely the Mi'ihen Highroad.

100%
There are a number of things that can be done on the airship to contribute to 100%.

After boarding the Celsius in Chapter 1, the player must speak to Brother, Paine, Rikku, and Shinra on the Bridge, and speak to Barkeep in the Cabin. The player must also rest in the Cabin (which also applies to all other chapters), and view the Journey's Shot in Treasure Spheres from Shinra's menu. Later in Chapter 1, when the player can select locations the player can talk to Brother and select "Confront him" to gain a percentage. The player also gains a percentage after Buddy tells the player of reports of an awesome sphere in Kilika Woods. All of the aforementioned events total 2.4%.

The player also gets percentage in Chapter 1 from recruiting O'aka, speaking to O'aka on the airship, and paying off his debts (before the Chapter 3 mission Secure the Agency!), recruiting Clasko to the airship, talking to Clasko in the Cabin once on the airship, and for watching Crimson Report 1 from Treasure Spheres after obtained Crimson Sphere 1 on Mushroom Rock Road.

In Chapter 2, the player gets percentage from resting in the Cabin and giving the sphere to the Youth League at the start of the chapter. Later, the player must start the mission to obtain three Leblanc Syndicate uniforms; and after obtaining them the player gets percentage for watching the scene where the uniforms are all worn. After the infiltration of Chateau Leblanc, percentage can be added by watching the discussion of the mission of Bevelle. All of the aforementioned events total 3.6%.

The player also gets percentage in Chapter 2 from recruiting Calli onto the airship, recruiting Clasko onto the airship, watching Crimson Report 7 from Treasure Spheres on the airship after obtaining Crimson Sphere 7, and dropping off Clasko at the old Monster Arena.

In Chapter 3, the player gets percentage from watching the initial scenes and also resting in the Cabin. The events on the Bridge before Kilika and Besaid, but before Djose also contribute to the percentage. The aforementioned events total 1.2%.

The player also gets a percentage for obtaining the Crimson Sphere 4 from Guadosalam and then watching the Crimson Report 4 on Treasure Spheres, and for obtaining the Crimson Sphere 1 in Bevelle and then watching the Crimson Report 1 from Treasure Spheres. The player also earns percentage for checking the Travel Agency in the Calm Lands for the CommSphere installation, and the upper floor of the Chocobo Ranch for the CommSphere installation there. This also helps ensure percentage is earned for the scenes in the locations in the next chapter.

In Chapter 4, the player gets percentage from watching the Crimson Report 2 and Crimson Report 3 from Treasure Spheres, speaking with Paine on the Deck, doing the Rehearshal's Shtarting? minigame in the Cabin after the Moonflow events, listening in on the crowd's arguments before the concert, speaking with Tobli to start the concert, watching the full YRP scene, watching the performance in the Thunder Plains, speaking to Maechen on the Bridge, and speaking to Leblanc in the Thunder Plains. The Chapter is also largely about CommSpheres and watching all the scenes add to percentage. The aforementioned events total 14.8%.

In Chapter 5, the player gets percentage from watching Crimson Report 5 from Treasure Spheres, speaking to Buddy in the Bridge, resting in the Cabin, speaking to Buddy in the Engine Room, receiving the Mascot dressphere after all Episode Completes, speaking to Brother and selecting a location to jump into the Farplane from, returning from the Farplane to the airship and speaking to Shinra on the Bridge, watching the scene with Brother and Buddy on the Deck, watching the scene with Cid in the Cabin, and returning to the Farplane then return to the airship and speak with Rikku on the deck. The aforementioned events total 5%.

The player also gets percentage from watching Yevon's Secret from Treasure Spheres after obtaining Baralai's Sphere from Guadosalam, recruiting Cid to the airship from the New Cave on the Thunder Plains, watching the scene with Cid on the Deck, watching the scene with Cid and Brother on the Bridge, watching Crimson Report 6 and Crimson Sphere 8 from Treasure Spheres after obtaining Crimson Sphere 6 and Crimson Sphere 8 respectively at the Via Infinito.

Al Bhed Primers
At the start of Chapter 1, Yuna can talk to Brother and get given three Al Bhed Primers while explaining how they work. Buddy will give the player another Al Bhed Primer.

At the start of Chapter 2, after watching the scene with Shuyin and Vegnagun taken from Kilika Woods another Al Bhed Primer is earned.

Shinra's Bestiary
Shinra's Bestiary is an option on the menu when interacting with Shinra. The option allows the user to view the enemy's they have fought in the past, although it does not include a large number of enemies and focuses only on fiends. Defender enemies are also on the list.

Final Fantasy X-2 features an Oversoul features. After defeating a certain amount of enemies in genus (which varies per genus), an enemy of that genus will "Oversoul". Oversouled enemies improve all the stats and spoils of the enemy. When an Oversouled version of an enemy has been fought its name will appear red on the Bestiary and the Oversoul version of the enemy will be documented.

Each bestiary entry will have an image of the enemy, its name, its HP, MP, Gil, and Type. Each entry will also have a description which is a short comment presumably made by Shinra. The same stats are given for Oversouled enemies, while the description makes a comment on how the Oversouled version improves from the normal enemy.

To add an enemy to the list the player does not have to defeat it, only encounter it. The same applies for Oversouled enemies. After encountering all Oversoulable enemies Oversouled forms, Shinra will reward the player with the The End Garment Grid.

Recruiting Clasko
Clasko can be recruited at two points in the story. The first instance is in Chapter 1 in Mushroom Rock Road, while the second is in Chapter 2 on the Mi'ihen Highroad. The purpose of recruiting Clasko onto the airship is to allow him to open up the Chocobo Ranch in Chapter 3. Both can be done on a single playthrough but neither technically have to be done for him to open the ranch.

In Chapter 1, the player can go to the Mushroom Rock Road. Here they must talk to Yaibal and accept the challenge to run the gauntlet. The player must then talk to Clasko. If the player runs on without talking to Clasko they will miss out on a percentage. The player must then do the Foggy Fiend Frenzy! mission. After this mission they must return to the first area of Mushroom Rock Cave (the area the player is taken to after using the Save Sphere) to find Clasko south and on the right of the path. After talking to Clasko, Clasko will ask to board the airship. If the player selects "The more the merrier!" he will board the airship and be found in the Cabin, if the player selects "Sorry, loser" he will not.

In Chapter 2, Clasko can be seen during a mission on Mi'ihen Highroad, however there are two alternate requirements for him being prepared to join the airship after. Either the player must have made him board the airship in Chapter 1 or the player must go to the Mushroom Rock Road on Chapter 2 and talk to him. After this, the player must do the Cuckoo for Chocobos! mission. Clasko will help out during the mission and the player will have the option to recruit him to the airship. He will be in the area with the Save Sphere the player is dropped at off from the Celsius. The player does not have to recruit him to the airship for him to set up the Chocobo Ranch, but it allows the player to start it on Chapter 2 instead of Chapter 3.

If the player did not talk to Clasko on Mushroom Rock Road on Chapter 1 or Chapter 2 and then does the Cuckoo for Chocobos! mission, he will not appear during the mission and he will not be available to board the airship. However, if the player then goes to Mushroom Rock Road on Chapter 2 and talks to him after doing the mission he will then run off and next be seen in Chapter 3 at the Monster Arena.

If Clasko was on the airship after the Cuckoo for Chocobos! mission, when the player enters the Calm Lands Clasko will head to the Monster Arena. He will then open the Chocobo Ranch. If the player does not pick him up on Chapter 2 but spoke to him on Mushroom Rock Road at any point, or recruited him in Chapter 1, then he will be at the Monster Arena and set up the ranch on Chapter 3. If the player does not go to the Monster Arena/Chocobo Ranch in Chapter 3 then he will still be there in Chapter 5 however the player will miss out on percentage.

If the player does not complete these prerequisites the player will not be able to catch chocobos and therefore not be able to receive items from sending them out to places in Spira. It also means the player will not be able to enter the ranch location, or the dungeon beneath it, nor will the chocobo's be able uncover the Fiend Colony dungeon on the Mi'ihen Highroad.

Recruiting Calli
Like Clasko, Calli can also be recruited during Chapter 2 after the Cuckoo for Chocobos! mission on the Mi'ihen Highroad. During the mission the player must catch the chocobo for her. After this the player must return to the Mi'ihen Highroad to recruit her. She will be in the area with the Save Sphere the player is dropped at off from the Celsius. Selecting the top option will do this.

When Calli is recruited to the airship she will reside in the Cabin on the farthest side of the bar-counter. She will remain on the airship permanently. Other repercussions of her being on the airship include not being able to suspect Calli during the Mi'ihen Highroad Mystery minigame and sidequest in Chapter 4. This does not prevent the player from getting Episode Complete as there are two other options that will still reward this to the player, and it will also allow Rikku to become available instead who will reward Episode Complete and the Ragnarok accessory.

Recruiting O'aka
O'aka can be picked up in Chapter 1 from the Macalania Woods after doing the mission Follow That O'aka. The Macalania Woods is a five-star difficulty rating location at the start of the game which may deter players from coming to this area. The player must go outside the Travel Agency where a scene will ensue and O'aka will be seen briefly. Following him into the woods will start the mission.

It is possible to get to O'aka without being in danger of random encounters by traveling up through the crystal-path, however during the mission the path will also contain random encounters. The player can buy the Charm Bangle in the Calm Lands from Open Air to avoid facing random encounters if they are too difficult.

He is found at the Campsite. The player must select "Let's hide him on the airship!" to bring him to the airship. If the player selects "Quick! Call the Al Bhed!" then a second menu will come up questioning the choice, "Okay, let's hide him" will bring him to the airship while "We're turning him in" will end the mission without O'aka on the party's airship.

If the player turned O'aka in during the first mission O'aka can be found in Chapter 2 on Bikanel Island in the Southern Expanse working off his debts. He will appear as a green X on the radar. If approached he will ask the player to board their airship again. "Sure" will take him on the airship while "Sorry!" will not. The player will fail the digging expedition if they talk to him.

The repercussions of not allowing O'aka on the airship is not seeing him in the game at all after this point. The player will see Al Bhed in the CommSphere on Chapter 4 instead.

O'aka's debts
If O'aka was recruited in Chapter 1 or Chapter 2, the player can find O'aka in the Cabin until the end of Chapter 2. Here the player can buy his wares to help pay off his debts.

When the player pays off O'aka's debts he will offer the party a heavily reduced price on his items. The quest will end at the end of Chapter 2. If the player has not paid off O'aka's debts by this point then he will remain on the airship until they have been paid off. As soon as they have been paid off he will leave the airship and the player will never get the discounted prices.

O'aka's debt is 100000 gil in the first playthrough of the game. In New Game Plus playthroughs the debt is what the debt was on the last playthrough plus an additional 1000 gil. This means if the player paid off all the debts on the previous playthrough it will only be 1000 gil on a New Game Plus playthrough.

An easy way to earn the money is in Chapter 2. If the player has earned 10000 gil they can buy data from the innkeeper in Guadosalam. The data given is at random, so if the player were to save their game before buying data they could reset their game. If the data's hints are "It's the last person you'd expect" and the second hint is "It's the closest person you can find" the party will be able to sell it back to the innkeeper. The price of the data is 100000 gil, which is the amount needed to pay off O'aka, however the profit will be 90000. At this point the player will be able to buy 90000 gil worth of items from O'aka, and then sell them onto Barkeep. From 90000 gil the player will return 25.5% of money spent which is 22950 which will repay the remaining 10000.

Due to the heavily reduced prices the player gets if they pay off O'aka's debt before Chapter 3, the player can buy from O'aka at 10% of an item's base-price and then sell it at the sell-price (25% of an item's base-price) for a profit. This can be repeated indefinitely so long as the player does not continue beyond Chapter 2. Despite not being able to sell straight back to O'aka, this tactic for earning money quickly is made easier as Barkeep is found just across from O'aka in the Cabin.

O'aka will leave the airship once paid or at the start of Chapter 3 already paid. He will be found at the Travel Agency at Lake Macalania. He will also then appear in Chapter 4 through the CommSphere, and later in Chapter 5. In Chapter 5 a scene will ensue with O'aka and Wantz and the player will get an Episode Complete for Lake Macalania (although this is not needed for the Mascot dressphere) and the player will be able to use both O'aka's and Wantz's shops.

If the player has not paid off his debts by this point then they will miss out on percentage and he will remain on the airship.

Moving the band minigame
At the start of Chapter 2, after watching the scenes on the Bridge, Brother will comment about hitchhikers he picked up. If the player goes down to the Cabin they will find the band in the corridor. After talking to Daraya the player can start a short mandatory minigame where the player will have to move each member of the band into the lift. The player must talk to Daraya, the one playing the drums and answer "Actually, I'm singing tonight...".

The band members will stand still and will move when the player character moves into them. The player must push them towards the lift. When a member is successfully in the lift Yuna, the player character, will jump away from the lift and an elevator-sound will occur. The minigame ends when the three band members are in the lift. An easy way to do this minigame is to push the band member against the wall and then to push them a long the wall until they get into the lift.

The player is not timed for this, nor are there any rewards for doing it, however it is mandatory for story progression.

CommSphere Network
During the events of Chapter 4, the player can watch CommSpheres. These were placed all over Spira in Chapter 3 and allow the party to contact people without traveling to the specific locations. In each place many scenes will unravel. Watching most of these will contribute to a percentage.

There are four opportunities to use CommSpheres. The first is at the start of Chapter 4, the second is after talking to Paine when she is on the Deck, the third is after the events of the Moonflow and the Rehearshal's Shtarting? minigame in the Cabin, and in Chapter 5. In each of these scenarios, additional scenes will be added to the locations to be watched. None of the scenes in Chapter 5 count to percentage, and many of the scenes found at the later stage of Chapter 4 and at the start of Chapter 5 depict the breaking or stealing of the CommSpheres.

Rehearshal's Shtarting?
The Rehearshal's Shtarting? minigame is a mandatory rhythm-based minigame played in Chapter 4. After finding Tobli at the Moonflow the player returns to the Celsius. If the player goes to the Cabin from here a minigame involving Rikku and Yuna will occur. The screen is split vertically, with Yuna on the left and Rikku on the right.

On the right hand side of the screen a regularly-changing image of a button will appear (either, , , or ) and on the left a yellow or red musical note will appear and disappear shortly after. To earn the most points the player must press the button shown on the right side of the screen in-time with when the notes appear on the left. Timing the red notes right will earn the player more points than the yellows.

The game scores the player for pushing buttons as quickly as possible when the notes come up, and extra points are scored for pushing the correct button. The game does not use a detection/prevention mechanism for pressing the button out of time. Because of this player can simply mash the button given on the right hand side of the screen to easily earn optimum points.

Point range, four prizes:

Crimson Sphere
The Crimson Sphere 5 can be obtained on the Celsius in Chapter 4. The player can receive it from Leblanc who resides in the Engine Room during the short explorable portion of the chapter after Yuna's concert. If the player attempts to talk to Shinra, Leblanc will go up to the Bridge and the player will miss the opportunity to obtain the item. If not obtained the player will have missed the only opportunity to receive the key item in the playthrough and thus will not be able to enter the Den of Woe.

Brother and Barkeep scene
To be able to view the Brother and Barkeep scene, the player must prepare from the start of the game. The scene occurs after the player has rested on all five chapters. The scene has Brother talking to Barkeep about his love for Yuna. Brother comments that he and Barkeep were born bachelors when Darling, Barkeep's girlfriend, walks in.

The scene (as well as resting on each chapter) adds to the percentage completion of the game. It also allows Darling to appear permanently in the Cabin. After this scene the "The Gullwings March" will play as the theme of the airship until the player does a Mission. After this point the player will also be able to rename the pets used in the Trainer dressphere.

Recruiting Cid
In Chapter 5, the player can recruit Cid to the airship. Cid can be found. The player can enter the Thunder Plains where they will receive the A Fallen Genius? mission. After finding the tenth tower, defeating Humbaba, and completing the mission the player can enter the New Cave. The player will find Cid at the destination point where the player will have to fight the Machina Panzer boss battle. After this Cid will board the airship.

Cid first appears on the Deck of the ship. If the player goes to the Deck he walks down to the Bridge. If the player moves towards him on the Bridge a scene ensues where he argues with Brother. After this he heads down to the Engine Room where the player can find him.

Musical themes
The theme that plays within the Celsius is "Sphere Hunter Seagull Group", called "We're the Gullwings" in the Luca sphere theater and on iTunes.

"Mission Time!" plays at times when new storyline missions are available. This is often accompanied with a flash of red and an alarm sound. The same theme is also the theme for when the playing is in the destination select menu.

At the start of Chapter 2, "The Gullwings March" plays continuing from the end of the previous chapter's events in Kilika Woods. This continues to play as the background music on the airship until the dancing performance later that chapter before reverting to the normal theme.

Etymology
(also historically known as centigrade) is a temperature scale that is named after the Swedish astronomer Anders Celsius. The degree Celsius (°C) can refer to a specific temperature on the Celsius scale as well as serve as a unit increment to indicate a temperature interval (a difference between two temperatures or an uncertainty).

This name can be compared to the name of the airship in Final Fantasy X, the Fahrenheit, another measurement scales of temperature.
