Evelina (The Fires of Pompeii)

Evelina was the daughter of Caecilius and Metella and the sister to Quintus. She was forced to join the Sibylline Sisterhood, a local cult of oracles influenced by the alien Pyroviles. She had herself breathed in the Pyrovile's dust and had psychic powers. The Doctor transported her, with her family away from their burning house in the TARDIS, so as to escape the volcanic eruption. The Doctor told her that the link with Pyrovile had been broken, so that she was no longer psychic. He also explained that her ability to see the future was due to Mount Vesuvius' eruption being so powerful (the Doctor told Donna it had the power of 24 nuclear bombs) that it cracked open a rift in time for a second and the effects echoed backward through time. Six months later she was living in Rome with her family and going out more as she was seeing a boy. (DW: The Fires of Pompeii)

Behind the Scenes

 * The Caecilius family (Caecilius, Metella and Quintus) were based upon characters used in Latin text books, in turn based on actual historical characters but Evelina was invented by James Moran so she could be a member of the Sibylline Sisterhood.
