Northern Thanalan is where the final phase of Operation Archon takes place, with the Eorzean Alliance besieging Castrum Meridianum in response to Gaius van Baelsar's ultimatum.

During Dreams of Ice, the escaped Garlean spy Eline Roaille is recaptured here by the Crystal Braves.

Spoilers end here.


Northern Thanalan lies along the southern border of Mor Dhona, in a mountainous area rich with ceruleum deposits. The extraction of this resource has resulted in the sky obtaining a permanently blue hue.

So begins the third phase of Operation Archon, which entails a frontal assault upon Castrum Meridianum, Gaius van Baelsar's seat of power. Forming the main thrust, the Immortal Flames will strike at the stronghold with all their strength, though this is but a feint. While the garrison's eyes are drawn outwards, you and your comrades must steal past its defenses and attempt to deactivate the magitek field which protects the Praetorium, the fortress within a fortress wherein the Ultima Weapon is believed to be housed.

With the magitek field now out of commission, the path to the Ultima Weapon lies open. While the Immortal Flames sweep Castrum Meridianum and suppress the remnants of the enemy garrison, you and your comrades must fight your way to the innermost sector of the Praetorium, there to locate and destroy the Ultima Weapon. Cid's airship, the Enterprise, will bear you to the stage of the final confrontation.

Alisaie is resolved to go through with her quest to vanquish Bahamut, though it means confronting her beloved grandfather, whom the elder primal has made his thrall. With Alphinaud's cooperation, an aetherial pathway has been established which will take your party to one of the two internment hulks that remain to be disabled. Your foray begins in northern Thanalan, at the set of Dalamud's talons situated in Raubahn's Push. Spare no preparation and expect fierce resistance.

At the depth of 6,835 yalms, you and your companions are greeted by a breathtaking sight: a colossal replica of Dalamud, believed to be the device which regulates Bahamut's regeneration.

Restored to his senses in defeat, Louisoix uses his final moments to send your party to the main bridge of the final internment hulk, there to banish Bahamut once and for all.

If you are to overcome this terrible foe, you and yours must be of one purpose. Join now your hearts and minds, and sally forth to bring the Seventh Umbral Era to its true conclusion─for the future of Eorzea!

Spawn conditions (if any)
Boss FATE. With One Eye Open 49-52 Dalamud's Talons (x25 y20) 15 minutes Defeat Arimaspi.
Since the Calamity, the workers of Bluefog have told stories of a terrible one-eyed creature who would come in the night to carry sleeping men away from their campfires, never to be seen again. No one believed them...until a high-ranking Ul'dahn noble was snatched from his caravan. Now the city–state wants this Arimaspi's blinker on a pike.
Battle FATE. Under the Nails 49-52 Bluefog (x24 y21) 15 minutes Defeat the basilisks.
Plans to expand the Ceruleum Processing Plant are in motion, with the next step being to clear the nearby land of the massive crystal protrusions known as Dalamud's Talons. To do that, however, the area must first be rid of the hostile basilisks who hunt there.
Battle FATE. Boom Goes the Ceruleum 49-52 Raubahn's Push (x17 y18) 15 minutes Defeat the grenades.
Ceruleum is a highly flammable substance, and even the tiniest of sparks could cause an explosion, which is why the Ceruleum Processing Plant in Bluefog is especially wary of voidsent grenades straying too near the storage and rendering tanks.
Boss FATE. Knock on Steel 49-52 Raubahn's Push (x18 y14) 15 minutes Defeat the vanguard prototype.
The imperial army's mad engineers have developed a new grade of armor plating for their warmachina and are already testing it out on their magitek vanguards. If the Grand Companies of Eorzea are to stand against the Empire, they must know the extent of Garlemald's defenses; thus, they seek adventurers to test their weapons on these mechanical beasts.
Item FATE. Reverse Engineering 49-52 Raubahn's Push (x18 y16) 15 minutes Deliver ceruleum engine parts to the Amajina & Sons draughtsman.
An engineering expert employed by Amajina & Sons seeks to uncover the secrets of the ceruleum engines which breathe life into the Empire's warmachina and will pay good coin for any engine parts brought back to him, regardless of their condition.

Spawn conditions:

  • Speak with the Amajina & Sons draughtsman.
Item FATE. Core Blimey 49-52 Bluefog (x22 y22) 15 minutes Deliver earth sprites cores to the Amajina & Sons draughtsman.
Ceruleum processing is a complex task that requires a stable environment so as not to disturb the highly unstable liquid. One way to reduce seismic activity in and around the plant is by reinforcing the area with earth sprite cores, and Amajina & Sons draughtsmen are always looking to purchase more.

Spawn conditions:

  • Speak with the Amajina & Sons draughtsman.
Boss FATE. The Red Baron 49-52 Bluefog (x25 y23) 15 minutes Defeat the bomb baron.
Fat on the ceruleum of the surrounding fields, the bomb baron has grown bold and now makes his way to the Ceruleum Processing Plant, intent on draining its tanks and then self-destructing in one brilliant blaze of glory, taking half of northern Thanalan with him. Stop the hot-headed voidsent before his plan can be brought to fruition.
Battle FATE. Just a Sip 49-52 Bluefog (x22 y23) 15 minutes Defeat the quartz doblyns.
Quartz doblyns have gathered near the Ceruleum Processing Plant in search of food, that food being none other than ceruleum. Amajina & Sons will not stand idly by and watch as their profits are sucked down by pesky soulkin, and entreat adventurers to deal with the problem immediately.
Battle FATE. East Meets Worst 49-52 Bluefog (x22 y24) 15 minutes Defeat the ahrimans.
For no apparent reason, a flock of voidsent ahrimans has chosen to harass the keepers of the east watchtower. Entrusted with more important tasks, such as watching, the soldiers have issued a plea to all nearby adventurers to gather and drive away the creatures─preferably to somewhere in the vicinity of the west watchtower.
Battle FATE. Twinkle, Twinkle Little Trap 49-52 Bluefog (x20 y26) 15 minutes Defeat the quartz doblyns.
Ever the pests, a gaggle of quartz doblyns has dug into a patch of land near the Royal Allagan Starway, where they wait for caravans carrying ceruleum back to Ul'dah for sale and export. Many of the caravans do not have the means of clearing the roads themselves and request the aid of able-bodied adventurers.
Escort FATE. The Ceruleum Road 49-52 Camp Bluefog (x21 y29) 15 minutes Escort the wary merchant to the Ceruleum Processing Plant.
A frugal merchant bound for the Ceruleum Processing Plant to discuss business was abandoned by the two bodyguards he hired in Ul'dah after refusing to give in to their demands for more coin. Now, but a few malms from the plant, he finds himself helpless, and seeks to employ an adventurer to accompany him for the remainder of his journey.

Spawn conditions:

  • Speak with the wary merchant.
Battle FATE. Dark Devices - The Plea 49-52 Abandoned Amajina Mythril Mine (x26 y22) 15 minutes Defeat the lunatic lambs.
A poor farmer named Addison claims his only daughter was captured and taken away by the Lambs of Dalamud─a frightening cult which, even after the fall of the lesser moon, still offers blood sacrifices to their false god in hopes of currying his favor. The farmer seeks aid in reclaiming that which was ripped from his hands.

Spawn conditions:

  • Speak with Twin-tongued Addison.
Battle FATE. Dark Devices - The Bait 49-52 Abandoned Amajina Mythril Mine (x26 y22) 15 minutes Defeat the lunatic lambs.

Boss FATE. Dark Devices - The Switch 49-52 Abandoned Amajina Mythril Mine (x26 y22) 15 minutes Defeat Milburh and Twin-tongued Addison.

Spawn conditions:

Boss FATE. Dark Devices - The End 49-52 Abandoned Amajina Mythril Mine (x26 y22) 15 minutes Defeat Milburh the Malicious.
