This is an example of what they call ‘gutter magic’ in Unknown Armies. Not adept-level, not avatar-based, all kind of coincidental, but works all the same.
You’ve seen the shrines on the highways, right? Sometimes it’s a bunch of flags on the overpass, or cups stuck in the chain link fence there that spell out a message. And sometimes it’s a forlorn-looking cross and flowers against a tree or some other landmark. You see them, you drive past, you maybe wonder a little about why people do that sort of thing. Well, the answer of course is: “Some people are passionate/obsessed” (depending on whether you agree with the sentiment being expressed, or not). And that original passion and/or obsession has nothing much to do with anything that the occult underground does. Oh, there are plenty of patriotic or bereaved occultists out there. No question about that: but when a roadside shrine is put up, it’s generally magically inert.
