Well, most of the actual Numbered detectives have work to do back home. So those of us here will have to make due, for now. Not that I could go about any of those other reasons, at any rate.

Mostly though... Besides the lights, we've noticed the emergence of creatures called Vermini. They're strange little things, which can apparently infest other life forms. Mostly other animals. Normal people don't seem to notice them much, but since you're not quite in that category anymore... You may want to keep on the look out.
