Lord Zack's Greyhawk
Also known as orcs, this race has a long history of conflict with the demihuman and fairykin races, and a foul reputation that is not entirely undeserved. It is important to note, however, that humans and other races are capable of just as much evil. Goblins are ugly by human standards and have skin of strange colors, ranging from a pale, sickly-looking yellow to green to a dark-reddish brown to black. They tend to have a stooped posture and broad, flat faces.
There are a variety of kinds of orcs, such as the stronger mountain orcs, and the weaker and smaller hobgoblins.
