When werewolves meet vampires

[High Priest Mikhal]

There is some old mythology which states that when a werewolf died, it had a good (bad?) chance of rising again as a vampire. I think the underlying thought was that werewolves either were possessed by evil spirits, or that they used evil magic to create items that allowed them to turn into wolves, so if they died as werewolves, they died in Sin and their souls and bodies were corrupted.

Since originally, the werewolf was a person who turned into a wolf if given the right trigger (such as putting on a wolfskin belt charged with the appropriate magic) and vampires could turn into various animals (such as wolves), it probably wouldn't be too weird to just have any werewolf who is killed and does not receive the proper rites rise as a standard vampire -- or any other kind of vampire you choose.

This is why lycanthropy and undeath (especially vampirism) are so confused in Barovian folklore.

It isn't exactly the same, but this http://rpg.drivethrustuff.com/product/7 ... 28PFRPG%29 includes a ghoul/werewolf hybrid creature, which might be a useful inspiration for a vampire/werewolf hybrid.
