This stuff is really all over the place. So, not only was he in the hall of heroes, but he also came from a different world? There were some references to it, but I assumed that it could have been referring to something in the hall of heroes. Also, there's a bit too many things going on in terms of his power. He has 3 types of mana that each scale differently and have their own personalities, he has the ability to grow his mana pools quickly, and he has a stigma that gives him even more abilities, in addition to more nuances about his power. Its getting to be a little obnoxious and pointless.
