An Orog is a crossbreed between an orc and an ogre.
They are a foot our two larger than an orc, but with much more muscle and pale yellowish skin. Orogs most often can be found in orc tribes, the tribe using their strength in battle. They aren't bright enough to lead a tribe and there for are content doing the heavy lifting and battling the foes of the tribe.
Orogs have been know to live among humans as well, but those that do, must fight down the darkness of their nature.
