Crossbone Isle



Crossbone Isle is an optional dungeon featured in multiple Golden Sun series, and is home to the strongest enemies and bosses in every game it appears in.

So far, Crossbone Isle has appeared in the following games:


 * Crossbone Isle (Golden Sun) has been around since the very first Golden Sun game. The final boss is Deadbeard, who held the title of "strongest boss" in that game.
 * Crossbone Isle (Dark Dawn) returns in Golden Sun: Dark Dawn. Deadbeard has been replaced by Dullahan, and among the treasures the island holds are the Charon and Iris summons. In Dark Dawn, Crossbone Isle cannot be accessed until players have defeated the game's final boss, or unless they use the Endless Wall glitch.


 * See also: Anemos Inner Sanctum, which fills a similar role in Golden Sun: The Lost Age.
