update:  I've added a little more information to the plot and also a list of the central characters to give you a better idea of where this story might go.  My idea is just to keep the BIG story like some background element that we may or may not explore in the immediate roleplay.  It is however something that drives a lot of the events that are happening.  Basically if you are familiar with Hellboy, this other thing is the "Ogdru Jahad".  In this setting they are... similar.  Essentially imprisoned ancient things.
