Theodore is the father of Constance and one of the ruling powers of the Knights Dominion, known as the "Sword of the Dominion" for his prowess in battle. He resides in Mirsaburg castle, where he oversees much of the knight's activities.
Saruin's minions imprisons Theodore and replace him with a doppleganger during "Theodore's Madness", and must be rescued from the Pagan Ruins by the player. At the end of the game he leads the knights into battle against Saruin's monsters at the siege of Estamir.
Temporarily recruitable in the Abandoned Keep during the "Pride of the Knights" quest
