Story
Before the events of the game, Castle Deist's water supply was poisoned by the Palamecian Empire, slaying almost every Dragoon and Wyvern.

Later, after the destruction of the dreadnought, Firion and his comrades come here seeking the help of the Dragoons. However, he only finds Elina and Kain in the castle finds out that they have all been killed, and only one Wyvern remains. To preserve the Dragoons and Wyverns, he is given a Wyvern egg by the last Wyvern, to take the Spring of Life in the nearby Deist Cavern. After the egg is laid, the last Wyvern dies.

Later, after meeting Ricard Highwind, Firion and his comrades travel to Deist along with him. There, he speaks to Elena and offers to raise her child. If Firion returns after Ricard is killed by the Emperor, Elena and Kain will leave the Dragoon castle and move on with their life, giving the party the Excalibur, the treasured blade of the Dragoons.
