Official Profile

A gallant Celtic hero, son of the sun god Lugh. His weapon is the might spear Gae Bolg. His good looks could be deceiving, for in battle he is ferocious, tearing down his enemies and wiping out entire armies. A freak accident at the Summoning Portal caused these demons with a different appearance to appear.
