Okay. It's going to take some time and mod discussion to sort out how to handle magic that powerful and complex, so until we've had a chance to sort it out, stick to lower-level magic: in 3rd Edition or Pathfinder terms, spells level 5 and below, no conjuration besides the gargoyles, & no spells which grant or employ telepathic or psionic abilities. We'll certainly permit more than that when we have everything figured out, but for now that seems the safest limitation.

For the demon magic, no demon-summoning or vision-sending until we've had a chance to discuss more.

And waiting on the Erian stuff is no problem.
