The Darkspear trolls are a tribe of trolls that were once part of the Gurubashi Empire. After the tribes of the Gurubashi split, the Darkspear trolls fled the Stranglethorn Vale and settled on the Darkspear islands, which they named after themselves. There, they encountered a group of hostile murlocs. Having defeated them, they found new enemies in humans that were in search of orcs. They were eventually saved by the Horde Warchief Thrall. The Darkspear Trolls and Thrall and his band of merry orcs would then be captured by Zar'jira. Thrall was able to free himself, the orcs, and the Darkspear trolls but was unable to save the Darkspear chieftan, Sen'jin. Grateful for the orcish aid to the Darkspear Trolls, newly crowned chieftan Vol'jin would thank Thrall and the Horde by formally joining their ranks.
