Salem is a playable character in Fire Emblem: Thracia 776. He is the only playable Loptyrian Mage. He is met in the game as an enemy, and Leif and his friends have to capture him in order to convince him to join their army.
Salem, despite being a member of the Loptyrian Cult, started to question their actions, which is considered an act of treason punishable by death. Salem is then forced to flee the wrath of the sect, and survives thanks to Perne's timely assistance. Salem then joins Perne's band of thieves, and can later be recruited into the player's army in Chapter 12x, provided that the requirements to enter said chapter have been fulfilled beforehand.
