Broken

The Broken, also known as Krokul in Draenei, are a mutated and devolved sub-race of Draenei who lived in Outland. They, like most of the orcs, fell prey to the Demons sinister influence and were changed by the corruption. Though they lost some of their former powers, the Broken still present a clear danger to all races through Outland. The largest known faction of Broken in Outland, the Ashtongue Deathsworn, is currently led by Akama. They where/are supposedly allied with the powerful Demon Hunter Illidan Stormrage.
