The Isle of Thisvi, also known as the Forgotten Isle, was a small island in the Korinthian Gulf in Greece which housed a vault containing Brontes, a hybrid beast created by the Isu as part of their Olympos Project.
Empedokles, a self-proclaimed 'god', visited the Isle of Thisvi at some point during his journeys. Hearing Brontes' bellows within, Empedokles was certain that the creature was in fact Ares, the Greek god of war, and thus one of his siblings.
During the Peloponnesian War, Kassandra travelled to the vault to with Empedokles in order to meet the 'gods'. Upon entering the innermost chamber of the vault, Empedokles was slain by Brontes, and engaged Kassandra in combat, falling to her blades. Kassandra subsequently recovered the artifact which seemingly gave the creature life.
