The official GemStone IV encyclopedia.
The dark orc obtains her name not from having dark coloration, but from her proclivity for seeking out dark places in which to live. In fact, the dark orc's body is covered by a fine layer of salt-and-pepper fur, with a preponderance of the lighter shade. Thick of skull and lacking good reasoning ability, the dark orc subsists on whatever creatures are foolish enough to find their way into her line of sight with no real concern as to how tough to kill or dangerous they might be.

An old description for dark orcs:
Massive and sullen looking, the dark orc glares and grimaces at all who come within its sight. Larger than the more well known orc varieties, there is rumor that an unknown power resides in this horrific appearing monster.
