Final Fantasy V/Tycoon and Chocobo

Tycoon
When you wake up you find yourself in an open area and sees Tycoon Castle in the distance. There is not much to do outside the castle, not even any monsters to fight, though you can spot some differences between this world and Bartz's World. For one thing the meteor is gone and for another there is river to the west that was not there before.

Tycoon Castle
Go to the castle and go inside; it looks the same as it was earlier. The chancellor greets both princesses and announces a banquet in their honor. At the banquet, and Faris (being called  take their thrones while the lords and ladies begin to dance. Krile gets some air on the balcony.

You cannot talk to Reina and Faris at the moment, so go outside and talk to Krile instead. After speaking with her, go back in and enter the King's Chamber. Check the book there for a flashback of the king trying to get Salsa to ride a dragon for the first time. He ends up leaving alone since he needs to get a doctor for the queen. As you leave the castle, wonders if you should not try to get Reina and Faris to join you, but they seem to be too busy with the banquet so you go on without them. As you leave the castle grounds a soldier come rushing in to say that the bridge over the river to the west is complete. Bartz wants to check on Boko, his chocobo from the beginning of the game, who was last recovering from a broken leg in the pirate hideout.

Cave
Cross the bridge to the west and head north to the pirate cave. Boko comes out and introduces his wife Koko. Now that you have Boko you can cross rivers without a bridge. This opens a large area to explore, but there still isn't much to do in most of it. If you dismount Boko you can go back inside the pirate cave and meet the pirates and Koko. You can go back to the castle but it is pointless to go inside with the banquet going on. Continue north, cross a river and follow the canyons west to reach Tule Village. Dismount Boko to visit if you want, but there is nothing new there except fresh gossip from the villagers. Follow the river west and go south into a canyon. Continue and eventually you fall into a hole in the ground as a monster attacks.

Once the battle is finished a rope is lowered from the opening. It turns out to be Faris who recently escaped from the banquet. She is upset that you left without taking her along. On the way out, gets a splinter.

Head south until you reach a cave and go inside. Boko is left behind at the entrance as you cross a bridge. Continue into the cave proper and find the last room of the Shrine with  on his back. After Bartz turns him over, explains Bartz's world and Galuf's world merged together when the crystals in 's possession had shattered. A thousand years ago the singular world was split into two separate worlds. An evil force named Enuo split the two worlds using the power of The Void. Twelve legendary weapons were used to defeat Enuo and the crystals were used to contain The Void.

Krile's splinter begins to hurt once again and it pops out and transforms into X-Death. He states that he destroyed the crystals so he could obtain The Void's power. Sure enough, with the two worlds merged, The Void begins to appear in place of Tycoon castle. Gill surprises the party by clashing with X-Death. Once X-Death regains his composure, he sends the party flying and makes his escape.

Library of Ancients
When you recover you're within sight of the Library of Ancients. You go in and discover the scholars from Surgate castle. The book, half of which was in the original Library of Ancients, and the other half of which was in Surgate, has been restored and you can now read it. You hold a conference to learn what you can from the book and plan your strategy. You need to recover the twelve legendary weapons used in the fight against Enuo. The Book says that the weapons are in Kuza Castle, and four lithographs are needed to get them. There is one lithograph for each element; the Earth lithograph is hidden with the spirit of the past, the Wind lithograph is in an Island temple, the Flame lithograph is below the ocean floor, and the Water lithograph is behind a waterfall. The ancients sealed their servants with the lithographs and they will be revived when the lithographs are found. Finally, you must throw the book into the gate to find the final seal.

Go upstairs and talk to the scholars on the roof; the one on the right you the. Exit the library.
