Hel if one if the Guardians of Cor. He is the ruler of death and the creator of the Afterlife. Hel is the leader of the so called "StarClan", the guide of all ancestors and the loving mentor of Cor's heroes Caliar, Oriol, Kerin and Astar. 

His age and sexuality are unknown, as well as his ethos. The only thing Hel is remembered by the living beings in Cor are his gentle nature and his strong moral compass.
