Osmond Cordae Locke is a paladin who is the husband of Aegle Locke and father of Lucius Locke, and the son of Oscar Locke and Melana Locke. He is the heir of Fotiacles Firemaster. He was entrusted by the Mad Clergies to protect and apotheosise a revenant they believed to be the reborn Gaea, but these hopes were shattered during the Battle of Survivor's Woods. She left his side afterwards. Osmond has since then been studying two tomes. He was possessed by a remnant of Mardük, which was then purified and removed from him. Twenty years later, in the Fourth Age, he is a noble of King Derek I Valencia's court, and has a wyvern to ride.
