I'm putting together a ttrpg that almost acts like the inverse "Call of Cthulhu", centered around playing a coven of Sorcerer Priests touched by the Other Gods. I was wondering if there are any more good books or stories that touch on that perspective in the mythos? The ones from the man himself I've read that I thought best fit were Through the Gate and the Silver Key, The Hound, Herbert West: Reanimator, and The Outsider. I've also read the Ballad of Black Tom and the Trials of Obed Marsh when it comes to outside sources.
