Story[]
WARNING: Section contains spoilers.
During the events of chapter 2 of the game, the seas of Illisa Bay in the north of Tiberoa are rumored to be terrorized by a Sea Dragon. When Dart and his group expose Lenus as the false Princess Emille, she steals the Moon Dagger and flees towards Prison Island. The group boards the Queen Fury to get to the Islands where the town Fueno and the village Lidiera are connected by the Undersea Cavern, which also leads to the Prison Island, where supposedly the sea dragon resides.
Dart and his group confront Lenus and Lloyd on Prison Island.
At Prison Island, Lenus meets with Lloyd to pass the Moon Dagger to him, as well as to communicate some candid romantic interest in him. However, Dart and his group interrupt the scene and subsequently fight with Lenus, who turns out to be the Dragoon of the Blue Sea Dragon and the mastermind behind the Sea Dragon Regole terrorizing Illisa Bay.
Trivia[]
The Island next to the Prison Island, where Fueno lies, and which is connected to Prison Island via the Undersea Cavern, is called "Sunorest Island" on an official artwork of the map of Endiness, however this name is never used in the game.
