A lifelong Martial Artist, Mamanu is the embodiment of the adage 'My Body is my Temple'. Years of competitive martial arts training and tournaments have honed him into a well-built physical powerhouse. During a championship competition with the mage Yaeger (who would later become Mamanu's mentor), time froze to the standstill as the fate of the Elder mage and his apprentice-to be become entwined together as the fought, weaving a complex web of interactions and potential that would culminate in his Awakening to the Lunargent Thorn.

Mamanu is a mid-30's male that stands tall at 5'9". He carries himself with a humble disposition, eschewing many trappings of the modern world, fashion, and excess. While he's not very actively social, he has made a lot of effort to connect with the members of his cabal, spending time and offering aid when requested of him.
