The following exploration videos show the Shatterspear or "Dancing Troll" Village.
As far as I know you can't kill Krah'ranik or any of the other named mobs in the troll village, you can only kill the shatterspear trolls and drummers. You can't gain/lose faction with the shatterspear trolls either so you can't declare war on them. But it's a nice place to go grind for a little money and runecloth, since few people ever go there. Just stay away from the dance party by the lake, if you hit one of them you'll aggro the entire group of like 15 or so trolls. Well, mages MAY be able to AoE the crap out of them and make it, but I'm a hunter so I don't know personally.
It is a little more trouble than it's worth in getting there though. It requires ALOT of slope navigating and I suggest a stack of nogginfoggers so you can get that 2 minute slow fall. Plus I tried to take a friend of mine there once who's a male NE, and he couldn't seem to fit through this spot behind a tree in felwood that you need to squeeze through to get there the way I do it. So yeah, plusses and minuses to the shatterspear village.
Leader: Unknown, but there are four trolls with green names in the Shatterspear village: Jory Zaga, Krah'ranik, Una Ji'ro, and Voriya.
Unknown. While some of this area could just be decorative for flyovers, there are quite a few named mobs here, leading one to believe that this area could eventually serve some purpose beyond our current knowledge.
A small, and very hard to get to, glade between Darkshore and Moonbrook is home to the Shatterspear trolls. Those lucky enough to have visited this area can attest to the merriment of the shatterspear trolls, who are always in a state of dance. For this reason, the area is often referred to as "Dancing Troll Village."
