Gray wolves originated in Eurasia during the Pleistocene, colonizing North America on at least three separate occasions during the Rancholabrean. Unlike dogs, which were domesticated from them, wolves are difficult if not impossible to tame and had a checkered reputation among humans, blamed for attacks on livestock and humans alike. Despite that, wolves were also widely respected and became a synonym for strength, loyalty, and teamwork. The nuclear holocaust had a limited impact on the common gray wolf, primarily in the form of freeing up land previously occupied for humans by their use. The lack of exposure to humans the post-apocalyptic world heralded has also enabled them to move past their instinctive fear of human beings.
The wolves steadily proliferated, carving out a niche in between other apex predators vying for the same resources and soon became a common sight in various wasteland areas, including New California (even with human civilization resurging). Although the nuclear fallout had a marginal effect on most wolf populations, isolated groups like the ones inhabiting the wilds of Mount Desert Island, have steadily succumbed to the twisting influence of radiation and other environmental factors.
Wolves are quadrupedal canines, much like dogs, and travel in large packs. They are substantially larger and stronger than the common dog. The lack of human presence for almost 100 years has made wolves lose their instinctual fear of man, making them much more aggressive towards humans they encounter.
Wolves tend to travel in packs, this can pose a significant challenge to low level players. Since they are stronger than wild dogs they can easily take down careless travelers, so it is best to be prepared before taking them on.
