Spellweaver
A powerful being of some sort that hangs around Mr. Knight because he is entertaining. Spellweaver is a demiurge and a master of mind-related magicks, among other things. He seems good-natured and personable, but clearly sees humans as characters more than equals. The true extent of his power is unknown, though judging by the title demiurge and his carefree attitude, he may be on a godlike power scale.
He is an accredited psychologist and acts as Mr. Knight's therapist, even though this is a terrible idea. One can infer that part of the reason the program exists is because he suggested it to Mr. Knight to curb his mental health crisis, but also because it would be interesting. The terribleness of that idea has yet to be seen. Reportedly loathed by Parker Knight.
Spellweaver is highly interested in the magical members of the party; he and Overheat spend much time together due to a shared interest in tabletop roleplaying games, and he is highly interested in her reaching her potential. He has a more tumultuous mentorship with Conjuress, who regards him as an annoying trickster mentor.
