Nerellanvir is a Bosmer patron of the Overlook Inn, the inn located in the city of Firsthold. If you talk to him at the inn while the city is overrun by Daedra, he'll say, "The Eight save us! We're surrounded! We're all going to die out here!" When spoken to after the siege, he'll complain, "I haven't been sleeping so well at night after all this. I'm not sure I ever will again, in fact."
