A rove is a hiveless vampire. It takes a great deal of strength for a vampire to separate from the hive. Roves have their own drones, and are still extremely territorial, though they can roam further from their territory than hive-bound vampires (usually they have free run of the city their territory is in). The older a rove is, the more mobile he is. The position of Potentate can only be filled by a rove.
Roves maintain an alliance with a nearby queen, trading duties that a queen's hivebound vampires cannot in return for the metamorphosis of drones. A rove will never enter a hive house except for this purpose.
