Karag-hoth

Karag-hoth is a troll kingdom on Upper Heartworld. The current ruler, Barg, came to the throne only recently, by defeating the old king, Arak Earthshaker, in personal combat.

It remains to be seen whether Karag-hoth will survive the transition: cohesion of troll realms depends the subjects respecting and fearing their rulers. That said, the young King Barg is huge, massively strong and evidently skilled in combat to defeat Arak, so he likely has the necessary qualities.
