   Summary

   Demon!AU. With Erik as a demon and Charles' family as excorsists/supernatural watchers.

   x

   Charles and Raven are told not to look into the darkness, because one never knows what will stare back.

   Being children, they do worse. They try to open a window, and instead open a door.

   They are not prepared for what steps through from the other side.

   x

    

   Elements from Constantine/Insidious, but only characters from X-men. Movie knowledge not nessecary.
