The game
Players portray the Forsaken, werewolves, known as Uratha, who are sworn to a duty to maintain a balance and prevent ingress between the spirit worlds and the material world. Any human who may unknowingly possess a werewolf heritage could undergo a First Change at some time in their life, though what triggers the metamorphosis is unknown. It is known that it almost never happens before puberty or after the age of 60. Following this Change, each character develops an Auspice, defined by what phase the moon was at during their First Change, and most join a Tribe or become a tribe-less werewolf known as a Ghost Wolf. Unlike traditional fictional werewolves, Uratha may change at any time into various forms between man and wolf, though they do find this easier when the phase of the moon matches their Auspice.
Uratha are fierce territorial predators who feel the compulsion to hunt. Many have trouble containing their aggression, hindering their ability to live normal human lives. Additionally, humans feel this aggression and are repelled by this feeling. Also, every werewolf is in danger of entering a violent Death Rage (Kuruth in the First Tongue). In this frenzied state the werewolf is a threat to everything, no matter whether friend or foe.
Uratha also possess an instinctive understanding of the First Tongue, the language spoken by their ancestors and spirits. Although initially rudimentary, many Uratha can eventually learn to speak the First Tongue fluently.
In the broader context of published setting material, the Uratha are a specialized form of were-beast in the Chronicles of Darkness setting, and belong to the so-called Changing Breeds (beings part human, part animal and part spirit). Among these beings, the Uratha are not the only shapeshifters, but are one of the breeds with the deepest spiritual connection. There are also other differences to the other Changing Breeds. However, the Uratha don’t have much contact with the other Changing Breeds and those Breeds mostly avoid the Uratha.
