I think all babies are evil, and you have to be really careful they eat the right food before they pupate, or else they metamorphose into evil adults. Or something, I don't know, I was sick the day they covered that in school.
Beware every space you walk through or touch in this city. Doors, gates, arches, windows, picture frames, the open mouth of a statue, the spaces between shelves. Beware any space bounded on all sides. All these are doors to other places.
