Ulan-Tan

Ulan-Tan was a Warlock philosopher whose ideas defied the Vanguard: Light and Darkness exist in necessary balance and must coexist, the Traveler sacrificed itself so humanity should heal it, and the war against Darkness cannot be won. The pamphlet "Finding Light in the Darkness" is attributed to him. He founded the doctrine behind the Symmetrists (Symmetrists' Balance). His views were vindicated by Prismatic; a grove on Io memorializes him.
