Oh, yes. I can admit to that. I remember setting up the ritual circle. Using several different sources of historical exorcism methods in order to fine-tune it. It took me a long time to do it, given the scope necessary for a god-- around the past year and a half?

I also remember that Chacu Challhua had manipulated the circle at some point...? But I guess Samasu wasn't bluffing about noticing the problem at the last second, if Chacu Challhua is gone.
