The Catapult, also known as Ancient Base, is a location in Final Fantasy V. It is an ancient hangar of the Ronkan civilization and holds a library and a laboratory inside chambers. It acts as an unofficial "base" for the Light Warriors, as there are no random encounters, there are beds to heal for free, and the party's various ships (namely the Fire-Powered Ship and the Ronkan airship) are stored here.
After chasing King Tycoon around Gohn, the party falls into ancient ruins. They find a teleport leading to the Catapult, an ancient Ronkan base on the island of Crescent. The constant activity of this base has been the cause of recent earthquakes, which caused the loss of the fire-powered ship.
Upon reaching the base, the party makes use of the chambers and the hangar, finding both the lost ship and a stranger ship. Cid and Mid fall into pitfalls in the chocobo forest on Crescent Island, and join the party in the newly found ship, soon to be identified as an ancient airship. Cid and Mid make it fly and a monster residing in the Hangar attacks the party. The party docks the airship again, leaving it to Cid and Mid to fix it.
After the airship is in top shape, the party leaves the Catapult, only to return when they find the need to ask Cid and Mid for information or in case the airship requires maintenance.
After Exdeath merges the worlds, the Fork Tower buries Catapult. The party will have to destroy it to rescue Cid, who was beneath it at the time of the merging. This time, Cid will modify the airship so it can submerge.
In the quarters, there is a separate room containing treasure chests that can be obtained as soon as the party discovers the Catapult, by pulling a switch in the left chamber of the quarters, which will open a passage to the treasure room. If the party tries to access the treasure room after the Earth Crystal shattered, the party will be led to follow a series of clues, presumably left behind by Mid, before having access to the room.
