Professor Orb
There was a procedure where one could create an orb holding all of one's knowledge on a few select topics. This would create a professor orb, which seems to have a life of its own... but it's complicated.
I really do try to make most of this original, but since Forgotten Realms is an integral part of the world I can't help if anything is used without formal permission, but is still "fair use" as I am just using this for my private games.
