hechizo telaraña que cubre vecindario

I shook my head and got back to the detection web.
As spells went, this one was pretty big, but it wasn't complicated. I'd created a long-term version of the same basic working in the neighborhood around my apartment, in order to detect approaching mystical entities. The one I wanted for the hotel was the same thing, but I didn't have to bother with setting it up as a long-term construct. A sunrise, or two at most, would erode the spell, but with any luck I wouldn't need it for any longer.
