Here's something I'm curious about. I don't know how true this is (if at all), but one thing I've heard from several people is that in UA there really aren't any monsters as such: no ghosts, no vampires, no demons, no Lovecraftian abominations. Rather, I've heard that the characters in UA are basically fighting other humans (who have magical abilities) and/or hallucinations of their own making. Is there anything to this?
The fact is pretty much all of supernatural that you will find is either human created or human adjacent (going is game semi-motto "You did it"), but there is non human supernatural out there.
There, for example, clockwork (clockwork creature create by the setting tech mages), persons (creatures created humanities feel of lack of identity in modern society).
There even Lovecraftian in esthetics (thing shoggoth) Unspeakable Servants, who you summon and bind.
This also might come from the fact that possibly most common (adn some of the most dangerous) supernatural the players can encounter Demons, who are in fact ghost of people driven by obsession.
This kind of fits with SH, where the monsters are supposed to the manifestation of psychological trauma.
