Kelgar was an orc that Thrall met when he was trapped in the internment camps. Kelgar told Thrall of the corruption of the orcs due to the treachery of Gul'dan, and how the old ways had been so much better for the Horde (thus being the first person to introduce him to the idea of shamanism and the spiritual cure that the orcs needed). He told him that the only one still thinking of embracing the old ways was the undefeated Grom Hellscream, Chieftain of the Warsong clan. He created a distraction by fighting the guards, allowing Thrall to escape the camp.

He was "demon-corrupted" with red eyes and, like many of the other orcs at the time, lethargic. He claimed that he could kill the guards easily, but he did not even have the desire to try to escape the camp
