The fey are mystical beings who dwell between worlds in normal status, but can travel to and from worlds on a whim. They have a classification system based on power, and can come from any part of the world, from China to Ireland. They resemble us physically if they wish to, but have powers beyond our imagination. They sometimes breed with humans and the children and have some of their parent's power. The fey are immune to vampiric powers and can not be called against their wills. Of course, there are exceptions to every rule. .
