From what we can surmise, I think it best to tell you our fears now so you are not surprised by future events if we are correct. We may be dealing with a possible devil possession. While this is a far better scenario than an actual physical manifestation of those suspected creatures on this plane, a possession is still immensely dangerous. Before we can attempt to chase it back to its own plane we will need to make preparations. First we will need to reduce its influence here on Alganon by removing those who are feeding it magical power. The High Shaman of the Arow'zi and the Sorcerer Lord of the Xu-tal are both bound to the creature through blood magic. Kill them and our hope is not yet lost.
