Meh, I am almost certain that most of the comments is stated on rumors.
I mean, what OFFICIAL information has said that GM's cant show em self?
I am sure that they shouldn't really do it, but I am sure they can.
From what I have heard, not what I know, they use a external program to
do everything. The character is just to talk to the players. How that GM
did get those spells, and that... Oh well, GMs do get items (Thinking about
the shoulders), so why not spells?
Oh well, I wish I was there to enjoy that show ><
