In Path of Radiance, Ike will find Sothe on his ship, and will allow him to join his team. In the game he is a thief, but is unable to become an Assassin. In the sequel to Path of Radiance, Radiant Dawn, he is a member of the Dawn Brigade like his best friend, another main character, Micaiah. His class is Rogue and he can wield Knives and open chests and doors without a key, like a Thief, or a Rogue in Fire Emblem: The Sacred Stones. He can also steal unequipped items from enemy units. He achieves his final class, Whisper, not by conventional means, but by completing the Prologue of Part 4. His knowing Micaiah is hinted at in Path of Radiance when he wants to go to Daein because he is looking for someone, who is suspected to be Micaiah.
