The Skullsplitter tribe split off from the Gurubashi empire after the defeat of Hakkar the Soulflayer. The various tribes claimed territories in the vast jungles of Stranglethorn Vale and quickly began fighting one another. The Skullsplitter settled in the ruins of Zul'Mamwe. These ruins are in the middle of the jungle, far away from the main road and directly south of Murky Depths Lake. These trolls are solitary and deal mostly with outsiders when they are visiting the Arena. They seem dedicated to shorting up the old ruins and building structures to fit their growing population. To this day the Skullsplitters fight off all interlopers, including the nearby Bloodscalp tribe, in order to hold onto the land they have taken. Skullsplitters have nothing but contempt for the Darkspear tribe, which is the only tribe of jungle trolls to have joined the Horde.
