The Clerical Underground and the Purpose of Its Transmission

There is something called the clerical underground. It's a bunch of monks who are too semi, mostly pretty privately, but not exclusively,. They have the time and resources to start summoning spirits which are a mixture of all sorts of spirits. So we know that monks are playing with this tech because again, they hit, they're the ones that have access to it. We also see that a bunch of texts for summoning demons, devils, unclean spirits also have little giveaways that show like in the timing.
