Mage: The Gun Quarter
An unassuming old man with an eccentric bent
Martin spent the majority of his life as a history professor, and had taken a young Art Valentine under his wing in the later days of his career when Art used their shared knowledge and love of medieval history and lore to actually find the holy sword Excalibur. This momentous discovery awakened them both, Art as King Arthur and Martin as his adviser and court wizard Merlin. The two traveled for a time seeking the rest of the Knights of the Round Table until forming a foothold in Birmingham.
Martin was killed by an emanation of the primordial spirit of darkness, Noh, The Prince With A Thousand Faces. However, his sacrifice allowed The Misfits and The Sleeping Dragons to prevail in their battle against The Ninube Clan.
