The drogbar are a race that live within Highmountain on the Broken Isles. It appears they have overtaken the Lair of the Earth-Warder and call Neltharion's Lair their home. Once slaves of Neltharion, they are now ruled by Dargrul the Underking.
They are a shamanistic, cave-dwelling species intent on ousting the Highmountain tribe and taking control of the region. To that end, they stole the artifact most dear to the tauren, thus causing their clans to fracture.
