Final Fantasy V/Airship and Mirage

Moore Forest
There's nothing more to do in the desert so head back east, but save your game and prepare for battle before entering Moore Forest. When you reach the Elder's Tree there is a cutscene. A dragon comes bearing Reina, rescued from Tycoon Castle before it was sucked into the N-Zone. But her body is possessed by an evil spirit, the monster Mellusion. X-Death appears and claims that Mellusion is just one of the many monsters from the N-Zone now under his control, and to demonstrate his power he sinks the Library of Ancients. The dragon appears again and somehow forces Mellusion out of Reina's body. X-Death leaves you for Mellusion to death with and a battle starts.

When the battle is over Reina start to recover, and rejoins your party. Use Raise or use a Tent to heal her before moving on though. Continue east; there is a big hole in the ground where the Library of Ancients used to be, but the ship spotted earlier is just to the north of it.

Airship
Go aboard to start a cutscene. Reina, who hasn't been in on the plans to collect lithographs, says the entrance to the N-Zone is where Tycoon Castle used to be. But Faris and Bartz say that they need to go to Kuza for the 12 legendary weapons, and you start for there. Meanwhile, X-Death, drunk with power, starts attacking the towns of the world and sinking them into the Void. From the airship you can see this happening but there's nothing you can do about it, though Bartz, in a rage, starts wildly driving the airship faster and faster. Eventually Bartz calms down and you're in control of the airship.

In all, four towns were sunk, but you can now visit the ones that are left. Of these, Tule Village, Town of Karnak, Surgate Castle, Moore Village have nothing new but updated gossip as already noted. There are six others, namely Kerwin Town, Jachol Village, Cescent Town, Lugor Bordertown, Val Castle, Kelb Village, but in all but one there is nothing new but updated gossip. The exception is Lugor Bordertown, where if you talk to the girl between the shops she will give you a Ribbon. You may want to visit the othe towns just for gossip since there are important clues.

There are ten other points of interest on the map. One is former location of Tycoon Castle which is now the entrance to the N-Zone. There is nothing stopping you from entering the N-Zone right now if you want to; just fly over the hole to be sucked in and start up the ariship to fly out again. The former location of the library of ancients is also marked, though there is nothing there now. There are four dungeons marked: the pirate cave, the Wind Shrine, North Mountain, and the Valley of Dragons, Go to the pirate cave and through to the pirate hideout, then after a short cutscene, you get Faris' old friend Hydra as a Summon spell. There is nothing new in the Wind Shrine, Valley of Dragons, nor at North Mountain unless you want to take on Behamut and that's not recommended at this time. (You can't reach North Mountain right now anyway, stay tuned.)

There are two towers marked, but these are dead ends for now, which leaves and the Sealed Castle and the Island Shrine. The Island Shrine is the location of the next lithograph, but we'll save that for a bit and go to the Sealed Castle.

Sealed Castle
Look for the castle east (about halfway to Torna Canal) and a bit north of Tule. Enter to speak to the scholars whom have previously arrived from the Wind Shrine. One of them so happens to have brought the recovery urn just in case you need to heal your party. Speak to the head priest if you need to refresh your memory on the Sealed Book or any further objectives. Continue north until you reach the Sealed Room. It is advised that you have Flee or Dustb equipped here if you're needing to escape from difficult random battles. The main area has the twelve legendary weapons arranged in a clockwise formation with the Excalibur at the top (12 O'clock).

Check the pedestal with the sparkling lights to place the lithograph; you can now unlock and obtain three of the weapons. Depending on your current jobs, some of these will be more useful than others, but you will get all of them eventually so there's no need to agonize over your choices too much. Take note that some jobs won't be able to use some of these weapons even when they would normally be able to use a weapon of that type. For example, neither BlueMage nor Red Mage will be able to use Excalibur. Since nearly any job will be able to use the Assassin, it's recommended that you get that one in the first round, and pick the other two according to what jobs you're planning use for the next lithograph. When you have selected the three weapons you want, check the pedestal again to exit. (The game does not let you leave without selecting three, so don't worry about missing any.)

There is a cut-scene in X-Death's lair. He speaks to the monsters from the N-Zone which is now under his control and lets them know he needs volunteers to fight the crystal warriors (meaning you) to prevent them from obtaining the lithographs. Three volunteers come forward which you will presumably see later.

Mirage village
Before going on to the next lithograph there is another optional area you should visit. You will hear rumors of a town hidden in the forest if you talk to people in Crescent. Head south and west, following the long isthmus. (This is formed from the island chains in the other worlds.) Explore the forest at the southernmost part until you enter a village. This village does not always appear in the same spot, so you may need to move around for a while before you get it.

Talk to the people to learn that this village was frozen in time in the N-Zone, but has been released now that X-Death is trying to unleash the Void. Before exploring any of the buildings, equip the Secret ability since there are many hidden passages here. You can stay at the inn for 70GP but you may later come upon a recovery urn if you're trying not to spend money. If you're able to afford such a luxury, the item shop upstairs sells Elixir for 50000GP each, but you may want to visit the other shops first before making that kind of purchase.

Go north and up some stairs to the pub for gossip. The Magic and Armor shops are south of the pub. The Weapon shop is down the stairs and to the west of this. The inventory here includes items and spells which either was not available in previous shops or are no longer available because the shop has disappeared. However, if you have been thorough about collecting treasure up to now, then you should already have most of these items already.

This covers the easily accessible parts of the village, but there are other parts which are not as obvious to find and you may have caught a glimpse of these. First, take notice of the door behind the bartender in the pub. Exit out of the pub to go around the north side of the building and keep looking for the hidden door; when you find it you may come in behind the bar. Check for treasure in the barrels next to the bartender then go down the stairs to a small room. Before exiting south, you can start the Chocobo tour subquest by talking to the strange fella in the room.

Go south through a tunnel and enter the nondescript building to the left of the Weapon shop. There is a healing urn here in case you decided to skip spending 70GP at the inn. As you continue north towards the stairs speaking with the villager will reveal that each store has two merchants. Since only five merchants have been covered up to this point, and this person is claiming there should be eight, that leaves three left to discover.

Once you've gone downstairs, assuming you've got Secret, you should see the hidden paths in the wall to the left. The first room has a stairway leading to a door; take note of this because outside is a black chocobo which you can either get now or come back for later. Go to the next room to the left where you may play the final piano (hopefully finishing off the Piano subquest.) As you begin heading back right, you'll discover the door in the main hallway is too dark and spooky to even consider entering. Ignore it and head upstairs if you're wanting to visit the secret Weapon merchant.

Make your way out of this area exiting through the pub and head towards the Magic shop. Aside from the obvious front door entryway, there is a secret side door on the left side of the building in the area where the pedestrian so happens to be walking. This merchant happens to have six brand new spells which are going for 10000GP each.

Now exit and head for the Armor shop. With Secret, you can see two hidden passages leading west from behind the counter. Check the north end of the counter and it will slide out of the way. Now you can follow the passage to the hidden merchant for the Armor shop.

Once you're finally done shopping, if you haven't already, you may want to head back through the pub and downstairs to catch that black chocobo from earlier. While the airship can get you to most places you may want to visit, the black chocobo will allow you to access the large desert in the northeastern part of the world map containing North Mountain and the Phoenix Tower.
