Final Fantasy V/Airship

Searching for the crystal
There don't seem to be any specific clues on where to go next, but even if you just wander around in the airhip at random you will eventually fly over Gorn Town, and this triggers a cutscene. There is rumbling noise and a huge spaceship rises out the sand and flies away. Gorn Town is now gone and replaces by desert.

This should be reported to Cid and Mid, so go back to crescent island and land on the grey square that marks the entrance to the airship hangar. When you arrive Cid and Mid are already aware of what happened. They've found a book that says the Earth Crystal is inside the spaceship and is being used to power it. Reina is worried that perhaps her father was piloting the ship, but can't believe he would do something like that. The airship can't fly high enough to reach the spaceship as it is, but if you can find Adamantite then Cid and Mid can attach it to make the airship go higher. Galuf says he remembers seeing some Adamantite on the meteor where he arrived. (Note, it's easy to miss this clue if you're in the habit of quickly paging through dialogs, and if you do it can mean hours of pointless searching for what to do next.)

It a good idea to go further into the hangar to rest and save, then go back to the airship and check the ship's wheel to take off. Land at Tycoon Meteor where the game began. When you approach the meteor Galuf presses a hidden switch that opens the door. Go in and check the blue rock on the far wall to get the Anamantite. As you try to leave you realize that the stone was guarded and a battle begins.

Go back to the airship hangar to find Cid and Mid waiting for you. Cid and Mid go to work installing it while go have a rest. Later, just as you're waking up, Cid and Mid announce that the airship is ready. But they've also learned that the floating ruins are guarded by cannons.

Now when press the button to land the airship you can also go higher instead.

Floating ruins
When you're ready, ascend to find the floating ruins; it doesn't matter where you do this since it will be waiting for you. There are four set battles here you must complete. At the top of each wing there are two cannons, simply approach one from the front to start a battle with it. For each battle you have to defeat two cannon-like monsters, either FlameThrow x2 or Rocket Gun x2. While not actual boss battles, and not very difficult, you do need to take them seriously. Use Bolt based attacks when possible. Also, one of your characters may get confused during battle and since at this point they can be as dangerous as the enemy you're facing, make sure you have a character with a weak weapon so you slap someone in the face without doing too much damage. It's a good idea to have the Learning ability equipped on one of your characters since both types of enemies have Blue spells. Finally, don't forget to heal between battles; in fact you can land temporarily to rest without affecting your progress. When you've cleared all four cannon locations there's a short scene where the final gun appears. Fortunately you can land to rest and or save before taking this on. When you're ready, take off again and start the battle by checking the gun in the middle.

There is now an opening into the floating ruins, but since is a dungeon you should probably land, rest and save before going in.

Ruins of Ronka
When you approach the opening the airship automatically docks in a hangar inside. Take the gangplank left to enter the ruins.

Finding your way around the first part of this dungeon is actually pretty straightforward, at least compared with some of the previous dungeons. You just have to realize that some of the floors are invisible but you can walk on them just like a normal floor. A way to tell is that if there is some kind of edge then there's nothing beyond, but if the tile looks the same up to where it appears to stop, then it's likely that the next tile is invisible. If in doubt, the Secret ability makes the invisible floors visible. In the lower levels there's a lot of running up and down stairs and changing levels, which can get a bit confusing but not if you keep track of where you've been already.

In the first room, head south through the door, circle west and through a second door, then down stairs to the 2nd Level. Go east, over a few of invisible tiles, then south to a longer stretch of invisible floor in the corner. Grab the treasure and exit south to the 3rd Level.

Here you start in the center; go to the southwest corner and cross an invisible bridge to the south side. Head west then north; there is a chest here which is a bit tricky to reach, but not impossible even without Secret. Follow the left path north to the northwest corner. There are a few ways you can go here, but start by continuing east and up some stairs leading north. This takes you to a small room with a save point. Go back and continue east, grabbing the treasure on the way, then go south down a stairway. This takes you to the 4th Level temporarily; go up another stair here to reach the east side of the 3rd level. Head north to get to the chest here, then backtrack to the entrance of the room with the save point. Follow the passage skipped earlier and take the stairs down to the 4th Level.

You enter a small room in the center; take the stair to the east to go back to the 3rd Level temporarily, then down another stair to the north section of the 4th Level. Take the stair south here to the 5th level. Go east, then south through a door and up a stair back to the 4th Level. Grab the treasure here, the go east to find two paths. Start by going down a stair to the 5th Level. Follow the corridor south, then back up some stairs to a room with five chests to open. Wait, did you think there wouldn't be a catch? There is a trapdoor between the two chests on the right; if you fall through then take the stair back up to the 4th Level. In fact you can use this as a shortcut.

Either backtrack, or go via the trapdoor. back to the northeast corner of the 4th Level. Take the door south and continue to a stair down the 5th Level, then take the other stair back up. Take the door to the south, go around the hole, which just drops you back to a previous section, and continue west. Go through the door, northwest through a passage to another door, turn toward the east and down a stair.

Now you're in the southwest corner of the 5th Level. Go south and circle to the east to enter a small room with another save point. Go back and take the door to the northwest. Continue to a stair that leads to the northwest section of the 4th Level. Take the door south to another room; this has two ways out at the south end. Take the stairs first to get treasure, the go back and take the door. Continue to a pair of statues and check the plaque there to open a stair down. Now you're in the final section and can see King Tycoon. Talk to him to start a cutscene there Reina and Faris both call to him, but he seems to concerned with a creature in the path ahead. King Tycoon steps out of the way and the creature attacks.

Afterwards, the king, with an evil laugh, thanks you for disposing of the creature, then leaves via the path that the monster was blocking. Follow him to the Earth Crystal chamber. The king is standing at the crystal and Galuf realizes that he's possessed by an evil force. The king is just about to attack when another meteor lands. A girl, Galuf's granddaughter, appears and knocks out the king with a spell. Galuf remembers her name is Krile as his amnesia heals. The king recovers and is no longer possessed, and has a reunion with his daughters. But in the end they were still too late to save the crystal and it shatters. With the seal broken, X-Death escapes from the forest where he was sealed and appears where the crystal was. X-Death tries to use the crystal shards to destroy your party, but only knocks out Bartz. Then he disappears heading for Galuf's world. King Tycoon absorbs the hostile energy from the shards and is fatally wounded. He tells his daughters to join their powers to defeat X-Death as he dies. Finally, you receive new Jobs from the shards, Samurai, Lancer, Dancer and Chemist.

The floating ruins, no longer powered by the crystal, start to disintigrate and you make a hasty escape to the airship. As Reina and Faris mourn their father, Galuf tells Bartz that X-Death was from his planet. Thirty years ago Galuf was one four dawn warriors who used the power of the crystals to seal X-Death away. Galuf and Krill now go back to Galuf's world using Krile's meteor.

The next time you land the airship, you decide to leave for Galuf's world to rejoin him and fight X-Death. There is no way to get there at the moment so the next step is to talk to Cid and Mid again.
