Tribe also has one sort of prey it is specialized toward hunting. These Five Tribes are: Blood Talons – the Tribe of Fenris Wolf, who promotes the warrior and wolf aspects of the Uratha. Their tribal ban is "Offer no surrender that you would not accept". Their favoured prey is other Werewolves. Bone Shadows – occultists who seek to restore relations with the Spirit Courts with the guidance of their patron, Death Wolf. Their tribal ban is "Pay each spirit in kind". Their favoured prey is Spirits. Hunters in Darkness – protectors of loci, the spiritual centres of the world. Black Wolf is their totem. Their tribal ban is "Let no sacred space in your territory be violated". Their favoured prey is the Hosts. Iron Masters – this Tribe, following the teachings of Red Wolf, embrace change and new ideas. They are closer to humanity, keeping up with technology and taking cities for their territory. Their tribal ban is "Honor your territory in all things". Their favoured prey is humans, along with the creatures that hide among them. Storm Lords – the Tribe of Winter Wolf seeks to lead all Uratha through strength and noble example. Their tribal ban is "Allow no one to witness or to tend your weakness". Their favoured prey is the Spirit-Ridden and Spirit-Claimed, material objects and creatures that have become possessed by spirits. Next to these five Tribes, there are the Ghost Wolves among the Forsaken who either never joined a tribe or left them behind. Therefore, they neither have a tribal ban nor a tribal patron. Some follow the Oath of the Moon and others do not; the only thing that all Ghost Wolves have in common is that they don't belong to the Uratha society in the traditional sense. Biology The Uratha are physical and spiritual creatures, who can use the energy of the spirits (called Essence) to activate certain supernatural powers (called gifts), supernatural tools (called fetishes), change form or accelerate their healing. Unlike humans, Uratha heal very fast (sometimes in a matter of seconds) and can theoretically regrow limbs and organs (which is accompanied with a great deal of effort). An exception to this rule are wounds caused by silver. These wounds have a resemblance to burns and only heal very slowly and with difficulty. The Uratha are immune against normal diseases and most foreign particles are expelled from their bodies
