The only spirts I know of that would be powerful enough to do anything like that would be the greater gods like the Unconquered Sun, or the Maidens maybe.

Or I suppose a big enough cohort of the fair folk. [She gives a single sharp nod.] That seems most likely. But they have to be straight up killed, not just banished, at least from what I've heard. Still, it's a lead. Might be worth working on.

[The convenience store description gets an offhanded shrug]
Ah. I usually just send a servant when I need something. Stores being open or not is their problem not mine.
