Vampire
Vampires have been presented both in infernal and dark faerie varieties in Fifth Edition. A magical version may well be possible, but a divine variety unlikely.
The upcoming sourcebook on the Transylvanian Tribunal will have a chapter dedicated to vampires and vampire hunters.
Vampires and House Tremere
In past editions of Ars Magica, House Tremere had members who had become vampires. This is no longer true in Fifth Edition canon.
