If you had met the man that I speak of, then you would have no doubts either. But I did not say that he lorded over it, nor founded it, only that I would not be surprised if he did. He is able to bend time and space, able to break the barrier between universes, and drag people between the two.
Needless to say, though, you are likely right. The Dawn Court I speak of are a group of people that are hell bent on bringing creatures that don't fare to well in the light, to meet the sun so that they might be destroyed by it, thus paying for their "sins".
