Vampire (mythology)

The Doctor met a bunch of vampires in Venice led by Rosanna Calvierri. The Doctor later found out that they were really Saturnynians. But most of the girls were in fact humans who had been turned into Saturnynians. They had to survive the process to become one. The Doctor described the ones in the dungeon Like Hudini,only he wasn't five creepy girls and will be shorter. The brides also break into Guido's house. They seem to have the ability to fly as the prove when then reach Guido's house on the second floor and they're hovering outside the window. But as the Doctor escaped with Amy and Rory, Guido stayed behind and blew the Saturnynians brides.
