Creature
Trolls
They never fight anyone. They just whisper, until everyone else does.

What they are
Trolls came through the crack that sundered the Reach and crossed into the waking world. They incite hate. They bring out the worst in people, then step back and let it spread.
They whisper into ordinary ears, feeding whichever sin each person is weakest to. A quarrel over nothing that lasts eleven weeks. A crowd that can’t say what it wants, only who it hates.
