A short summary of the book:
As the title says, Monte has created his own version of the World of Darkness setting with d20 rules. There are rules for playing Vampires, Werewolves, Demons, Mages and a new archetype called Awakened which is a very competent human who somehow anchors reality.
The powers functions like a variant kind of feats. Demons have Cants, Mages have Gnosis, Vampires have Disciplines, Werewolves have Rites.
Mages create spells with Components. A Component is a point cost for casting the spell and the Spellcraft DC.
