The hyperborean realm of the Eternal Flame
Clarence was singing in harmony as his kind is wont to do. Their singing reinforced the "song of existance". It was a somewhat important job, even though only a handful were needed rather than the hundreds that did so. He and others near him noticed the pin prick discordence in the weave of melody that was the material realm. Those dark alien notes rose up. The Angel Mind touch the Divine and followed the new sub melody. Humans would call it a plan. Angels dove to the material realm and, of course, if any world was going to be causing problems, it had to be Earth. Oh well, at least Clarence would know his way around.
Ten powerful magic rings created by an Archmage have scattered to ten random people (suggest only one is PC). This happened when he died in battle. Whoever gets all ten rings inherites all the power the Archmage invested to them over his 200 year life.
