For many years, the orcs had been entrapped within internment camps, seperated from the rest of their brethren who, while free, were facing life nearly if not rougher than that withn the camps themselves. That is, until a remarkable young shaman soon came upon his people and became the first shaman of a new generation that the elemental spirits accepted. Soon, this newcomer - branded by the humans with the name "Thrall" - proved to the clan his capabilities when he was able to best Orgrim Doomhammer in single combat. Vraul, hearing of the plan that Doomhammer and Thrall had concocted against the humans, was eager to join in on their idea.
It was not until Durnholde Keep that Vraul was allowed to fully join in on the attack, but the wait left him extremely hungry for battle against the humans. It was there, within Durnholde, that Vraul would meet an orc prisoner, Aknug Stormrider, and personally free his bonds so that Aknug was able to join in on the fight against the human wardens. The battle was bloody and not without casualties, and Vraul himself suffered severe wounds throughout its peak. The most damaging were to his shoulders, which were hammered with maces that broke off the chains of his spaulders, as well as swords and daggers that cut deep into his skin. He was also blinded by a dagger being pierced into his right eye, which forced him to wear an eyepatch afterwards. Nonetheless, the orcs were successful in their attack, and the imprisoned orcs had been freed. All that was left in the end were a pile of corpses and rubble from the keep that Thrall brought down with the might of his shamanistic powers.
