Edge Master has a mysterious past; he is renowned for his skill with various weapons, and his past and real name are known only to himself. He served as adviser and teacher of Ling-Sheng Su martial arts at Ling-Sheng Su Temple (???) -- who would descend from the mountain only to participate in the temple's holy artifacts succession ceremony and train their inheritors-- before he burned it down following the fateful night of the Evil Seed. Edge Master found Kilik, the cursed successor of the Kali-Yuga, in the temple and taught him to suppress the evil within himself over a three-year training session. Once Kilik had completed the training, Edge Master gave him the final test of destroying Soul Edge; but after Kilik left on his journey to purify himself and the Kali-Yuga, Edge Master began to feel uneasy. Although his motives are unknown, he broke his silence and departed on a quest of his own.
