1) Is it possible that the Vampire-looking "messiah" in the murals is really the Hylden-possessed Janos and that the Hylden-looking savior is really the combined Kain/Raziel entity?
2) Was Mortanius possesed by the Hylden when he raised Kain? If so, is it possible that he was then "raising" the Hylden savior"?
3) At the end of it all, what is that the Elder God really wanted to have happen?
