Brief description of the Anitaverse...
Okay. The books are set in something close to the present day, in a universe where all sorts of 'preternatural' beings and critters exist. Vampires have become legal citizens in the United States, so they cannot be killed unless they commit a crime, but mind-control or feeding without some reasonable degree of consent is a crime. Vampires are territorial, with a Master of the City, and a group of subordinate vampires. Vampires increase in power as they age, but not all are reborn equal. Some will become Master vampires, some never will. A Master vampire will gain additional powers of the lineage, such as the ability/need to feed from lust or fear, and to 'call' a type of animal... including a lycanthrope of that species. Lycanthropy is a virus, and has much of the same stigma as HIV. Lycanthropes also grow in power and control over the first few years of their 'condition', with some becoming alpha and gaining additional abilities, and some remaining beta. Those abilities include partial shifting, the ability to calm or force a change in other lycanthropes, et al. Wolf lycanthropes have a very organized pack structure. A lycanthropic oddity is a panwere who was initially infected with more than one form of HLV before the first full moon after initial infection.
There also psychics, wiccans and hermetic mages, voudou priestesses, and Necromancers. A necromancer is someone who had the innate ability to raise the dead as zombies, and a master necromancer can gain control of non-master vampires. In addition, faeries or the sidhe exist, but the universe isn't the same as the Merry Gentry series that focuses on the sidhe, so it's arguable whether the faeries of the Anitaverse are the same as those in the Merryverse. There are also semi-sentient trolls here and there in the world, sub-sentient dragons in Europe and Asia, and creatures of Hindu myth that have appeared in the books.
One of the most powerful situations is a triumvirate, where a vampire 'marks' a human (including one with a magic or psychic gift) and a lycanthrope of that vampire's animal to call. Strengthening of existing powers and some blending of each type of power gradually develops from this. Recently, Anita, a powerful master necromancer, created a second triumvirate with a lycanthrope and a vampire.
So, that's a little taste of the universe. There are a few inconsistencies here and there in the books, but there has been enough discussed to allow a decent structure and the potential for rules lawyering.
If we get a nice-sized group interested, I could probably be persuaded to lead a game.
