There is a vendor out on the tundra not too far from Permafrost on one of the old fallen building structures. Not sure what faction they are. Either they are a shaman spell vendor or normal Halas merchant faction. No other npcs or guards around them. Might just be able to kill a ton of gnolls in blackburrow and sell to them.
