There's an environmental dread effect at Nindor, of +3 dread, but only up on the ruin platform where Brudhraw spawns.
There are other mobs immediately around the ruin, (and it still says Nindor on the radar.) These are: Bloated Muck-Crawlers, Slimy Muck-Crawlers, Ancient Bog Wardens, Noxious Bog Wardens, Bog-Warden Archers, and a Bog Lord.
