Trog (Fallout 3)

Trogs is a name for mutants that used to be human, but after the Great War slowly devolved into scampering troglodytes who fear the light. Similarly to ghouls, some of them retained more of their humanity, while others became more animalistic.

Biology
The skin of trogs is a dull yellow/white, as well as their hair (in case of those trogs who do have it), as a result of the loss of melanin. The trade-off is that their skin got a tad thicker, which made them more resilient to cold and hardships. They are, however, very sensitive to sunlight.

The Pitt
There is a population of trogs in The Pitt - the ruins of what used to be known as Pittsburgh, Pennsylvania. Due to cruel treatment from the raiders and further mutations thanks to the town's high contamination they have devolved even more, crawling on all fours and attacking all surface-dwellers on sight. They are known to hunt in packs.

Hoover Dam


The trogs of Hoover Dam, while not pleasant to look at, are much more human than their Pitt counterparts. They 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.

History
Before the Great 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 decided it might be a 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 well. 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 bit. 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.

Since then, the name has also been used to refer to other originally human mutants that are sensitive to light, even if they've devolved into mindless beasts and have nothing in common with the barely civilized, but still mostly human descendants of hillbillies.

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.
