Shifter

Shifters, the ancient race of beings born of those truest to the wild world. In ages long past it was said that the Shifters were collections of Elves, Humans and Dwarves and other mortal races who all fled to the wilds, away from the holds of civilization, to heed the call of the God of Animals Totema. Totema was said to be the creator of the "Beast Races", but wanted to bestow the gift onto mortals across the world. So during the End of the Divine Era, Totema called to the Mortals who would listen to come meet them in the wilds. Those who did were given a gift before the Gods left the Mortal Plane, the gift of animalistic instinct.
Their skin could harden to hide, their nails turned to claws, and their teeth grew to tear and gnash at enemies. Through history they had many names, Traborn, Beastfolk, Wild Born, but in time the common place name Shifter was their calling card.
They can now be found in many places in the world, especially in the wilds. Shifters culturally stray from society, believing it to be a fragile structure and not intended for long term survival, only short term cooperation. They believe everyone must learn the wilds, for to reject them is to reject your very being.
Shifters don't form tribes either, believing that a tribe while natural in its location, is still but a crux of civilization that one might cling to. It is best to learn the wilds alone. This means that the general world at large does not really take notice of these natural born wanderers, they simply live a hermits life style alone.
