A roughly two thousand year old vampire created by the ancient vampire Arion. Petronia is intersex having both male and female genitalia. Petronia was a powerful gladiator in Rome before becoming a vampire. Petronia lives in the swamp next to Blackwood Farm, because the island there was given to her by Manfred Blackwood, one of Quinn's ancestors, and also one of Petronia's fledglings.
