OK, so apparently I had been to Dawnstar a few saves back and missed some real action, just hopped back in to start the Razor quest, and I'm greeted by the kajit's standing around a body saying "Oh my, what happened...". So I look and it's the body of Abelone, with the bodies of Fruki, Lond, and two guards nearby. I walk through the town and there's another dead guard, Irgnir's dead along with two dead vampire thralls, then again near the inn another dead guard and a deceased master vampire.
I think the main reason for this DLC was to secretly cut down on the frivolous amount of NPC's living in the world.....
Edit...on the 360 version......
