There, they defeated Rubicante and avenged Edge's parents. However, a trap door in front of the Crystals dropped them back to the subterranean levels! They found an airship, named it the Falcon, and escaped to the Underworld. However, the Falcon cannot fly over magma. The party's next stop is the Dwarven Castle.

The party resumes outside the Dwarven Castle. They enter the castle.
Dwarven Castle (time 0:56):
The party heads to the Throne Room. A scene takes place when they approach King Giott. He is worried that Golbez will succeed in breaking into the Sealed Cave, so he wants the party to go there and retrieve the Crystal. He gives them Luca's Necklace, the key to the cave.
Downstairs on B1, they take the western door into the Infirmary. There, a scene takes place when they approach the bedridden Cid! How in the world did he survive? He even has the energy to upgrade the Falcon so that it can cross the magma. After the upgrade, the party finds his letter. Enclosed are his augments: Adrenaline, Upgrade, and Analyze. Nice!
