What is it really?
The main idea of Werewolf is that the Garou (werewolves) were created to defend the earth from the cosmic forces that threaten to tear it apart. The Garou fight against the Wyrm, the destroyer. It is a struggle against nearly insurmountable odds, especially considering the rivalry between many tribes. These rivalries make it almost impossible for the werewolves to present a unified front against a cosmic force that pervades reality.
From this morass of hatred and mutual betrayal, there is little hope that the Garou can emerge triumphant against a foe so well armed as the Wyrm. The Wyrm promises money, power, sex, and whatever else the heart desires to its followers while the Garou receive no reward for their striving. It drives them deeper and deeper into despair, or into betrayal so that they choose to serve the Wyrm instead.
Cosmology
The three main spiritual forces in the World of Darkness are the Wyrm, Weaver and Wyld. The Wyld is raw unbridled creation. The Weaver spins reality into patterns. The Wyrm is supposed to destroy the excess order or the excess chaos. However, the Weaver went insane and tried to spin all of reality into its web, including the Wyrm. This drove the Wyrm mad so that it now seeks not to balance, but to destroy everything. The Wyrm has many agents and many faces, all bent on the utter destruction of Gaia, the Earth. The Garou are fighting to keep the Apocalypse from coming, but they are dying out and losing the war. Some tribes believe the coming Apocalypse will be the end of everything so fight desperately for even the smallest victory. Other tribes believe the side that wins at the final battle will be able to reshape the world in its own ideal. Some Garou blame the Wyrm for all evils and some blame the Weaver for spinning the world into stasis. Thus the Garou can agree on nothing and will not provide a unified front in the coming End Times.
The Garou
The Garou (werewolves) believe themselves to have been created by Gaia as her defense against the Wyrm and Weaver. They are the ultimate predators in the World of Darkness. They revere the Wyld but are also steeped in millennia old traditions. They are fighting to survive in the modern world, but cling to the old ways. Adding to their troubles is the fact that only one in ten offspring of a Garou turns out to be Garou themselves. Worse still, their kin, the wolves, have been nearly hunted to extinction, leaving them with very few wolf mates. Thus they have had to make do with humans, thinning the primal instincts of the Garou so that a Homid Garou may never have seen a forest until after his First Change. There is one way to guarantee Garou offspring and this is to mate with another Garou. However, due to an ancient curse laid on the Garou, any offspring produced this way are deformed and sterile. Thus they need to take their chances with humans and wolves to continue the line.
The Garou are a divided people, divided along lines of breed, of auspice, of tribe. Each Garou has a breed, auspice, and tribe and this means that they are not even uniform along a single trait! A Lupus Ahroun Child Of Gaia is a far different creature than a Lupus Ahroun Shadowlord even though they share two traits in common. The most severe divisions are between tribes.
The Breeds
Homid: These are Garou who were raised in human society, never knowing their heritage until their First Change. They often have trouble dealing with the wilderness and the spirit world. They are however deeply knowledgeable of human society and understand most technology. Homids are the most common breed.
Metis: These are the deformed and sterile offspring of two Garou. They are perhaps the best balanced of the breeds being equally likely to understand the wilderness or human technology. Additionally, their natural form is Crinos, the man-wolf form, granting them great battle prowess. They have the advantage of being raised in Garou society and thus know its often quirky ins and outs. Once they were the rarest of the breeds. It's a sign of how desperate things have become that in some tribes, they are more common than Lupus.
Lupus: These are born of wolves and have a deep primal connection to Gaia. However, they are sadly out of place in the human world, having little understanding of human society. Some never even learn to speak a human language. Most hate technology and often blame humans for all that is wrong in the world.
Auspices
Ragabash: Those born beneath the new moon are the tricksters and fools of Garou society. They challenge the Garou's traditional ways in order to help discard traditions that are outdated. Their tricks and pranks teach wisdom and humility to those who would listen. However, most Garou have little respect for the role of the Ragabash and consider them little more than pranksters.
Theurge: Those born beneath the crescent moon are the mystics and seers of the Garou. They have a natural affinity with the spirits and can speak with them, either persuading them to join their cause or forcing them to do their bidding like sorcerers. They are often associated with healing as well.
Philodox: Those born under the half moon are the arbitrators and judges of the Garou. They are charged with keeping the traditions of the Garou. However, they also strive for balance and harmony amidst the hot tempers of Garou. They are often jacks-of-all trades and can speak with the spirits almost as well as a Theurge, yet fight just as well as an Ahroun. The Philodox are the traditional leaders of the Garou.
Galliard: Those born beneath the gibbous moon are filled with passion that bursts forth in glorious song and hot tempers. They are the warrior-bards of legend taking time out from their art to fight and from their fighting to sing rousing tales. They are often joyous and make good company, usually.
Ahroun: Those born beneath the full moon are the natural warriors of the Garou. No Garou is incompetent at fighting, but the Ahrouns excel at it. They often lead the Garou during times of war or when there are no Philodox in the pack.
Abilities
Garou have several special abilities. They heal damage incredibly fast, and can be killed by little but silver or the claws and fangs of other supernaturals. They can change shapes at will and step into the Umbra, the spirit world. They have something called Gifts, which function similar to magic spells, or special abilities. They are generally instantaneous effects. This can be anything from being untrackable to conjuring a fireball to the ability to speak with animals. Each Breed, Auspice and Tribe has its own set of Gifts. Common to all Garou are Rites, static magic that requires specific things to be done to invoke them and have bizarre effects. A common Rite is that which allows you to change form without shredding your clothing while a rare rite allows a group of Garou to build a caern, a gate between the physical and spirit world. Rites take time to learn and to enact.
Rage
It is a gift of madness from Luna (the Moon) that allows the Garou to do truly spectacular things. Too much Rage is bad and will break loose in frenzy, a maddened state where the Garou loses all control, either Berserking or Foxing. In a Berserk the Garou attacks everything in sight, friend or foe. In Fox, the Garou flees in terror and will do anything to get away. Truly horrible frenzies are known as going into the Thrall of the Wyrm. Homids in thrall will eat fallen enemies (or packmates), Metis will do perverse and twisted sexual things to enemies and packmates, and Lupus will attack and destroy any who can't defend themselves, particularly packmates. Thrall is never good.
Gnosis
Gnosis is similar to the Polynesian concept of mana, or the Eastern concept of chi. While all creatures have some spiritual component, Garou can consciously control and use it. Garou are quite literally half-spirit already and Gnosis reflects how connected they are to their other half. Gnosis can't be precisely measured, but if you think of it like water, it makes comprehending the difference between a Garou and a human easier. A human has a cupful to last a lifetime, a Garou has access to an endlessly replenishing river.
Gnosis can be used to bribe spirits, activate fetishes (magical artifacts) and Gifts, and to enter the Umbra. Creatures without enough Gnosis generally cannot perceive or enter the Umbra.
Gnosis is a renewable, but dwindling, resource. Garou can regain it at sacred sites, by meditating, or bargaining with spirits. Sacred sites provide Gnosis, but if they become defiled, it can corrupt the Garou, or there simply may be no more available. The water analogy works well here. They need water, but they need to protect their sources because drinking tainted water may make them sick, and if they aren't careful, their well may go dry.
