Trog

Trogs are a race of people that used to be human, but after the Great War slowly devolved into scampering mutants who fear the light.

History
Before the big war, there were hillbillies. These people lived far away from civilized folk and fended for themselves in the wooded mountains. During the war, a lot of hillbillies reckoned it might be a plum good idea to head for the nearest caves and wait out the fiery mushrooms. Since the hillbillies were far removed from a lot of the nuclear blasts and subsequent fallout, especially being holed up in caves, the hillbillies fared pretty darned good. In fact, the hillbillies took to cave dwelling so well, they made caves their permanent home. Over the course of a couple of centuries, the isolation from the light, combined with ever so slight radiation that drifted over the world and managed to seep into caves, caused the hillbillies to change a slight bit. Their skin became a dull yellow/white, as well as their hair, as a result of the loss of melanin. The trade-off was that their skin got a tad thicker, which made them more resilient to cold and hardships. So, when some of the hillbillies first ventured out from their cave dwellings after two-hundred years, it came as no surprise that they could not tolerate direct sunlight very well. Smarter folks who saw the hillbillies started referring to them as troglodytes, but since most people of the wasteland were comprised of ignorant twits, the term "trog" became more accepted. Even the hillbillies referred to themselves as trogs.

The Pitt
There is a population of Trogs in The Pitt - the ruins of what used to be known as Pittsburgh, Pennsylvania. They are mostly hostile to non-mutated humans.

Hoover Dam
The trogs of Hoover Dam were nomadic at one time thanks to a cave-in at their previous dwellings. Before Dodge and his troops came to Hoover, Billy-Bob and his trogs took up residence in Baseline, figuring it was pretty secure from caving in. No one argued with the trogs, and when Dodge came to Hoover, he asked if they would help out Otto with the maintenance in exchange for food goods and water. The trogs accepted and have been content ever since to mosey around Baseline making sure every light was flashing correctly.

Appearances
The trogs were to appear in Van Buren, the canceled Fallout 3 by Black Isle Studios, and are going to appear in The Pitt DLC pack for Fallout 3.
