I'm also very confused about his/her role. As far as i know, he/she originated from a Bodhisattva (a sort of Buddhist Saint) named Avalokiteshvara. According to the JOS, he is supposed to be Loki. However, i doubt that he/she is on our side, considering, not only that he originates from Buddhism, and also the fact that it was (((Mageson))) who linked him/her to Loki. Therefore, i think is the best to avoid him/her.
