Vampires

The Vampires were undead beings.

They may have been purely legendary. In any case, Brianna Barter denied being one, and playfully bit someone on the neck. Presumably, their habits are assumed to be "standard": blood-sucking, fangs, etc.

Roger said "a vampire takes blood, and offers death"; and later Baron Daelrath suspects Brianna (as Valkura) a Vampire, so they probably do exist. Based on Daelrath's subsequent conversation, the vampires are cold and light-sensitive.

On occasion, Brianna Barter thinks of herself as a kind of sexual vampire, draining energy rather than blood.
