Sibylline Oracles
From Tardis Wiki, the free Doctor Who reference
Sibylline Oracles were the members of the Sibylline Sisterhood. The Oracles possessed psychic abilities which they believed were a gift from the Gods, they actually had the powers because they were inhaling Pyrovile Dust which was ultimately changing them into Pyroviles. A Sibylline Oracle could be recognised by the eyes painted on the back of both of their hands.
Notable Sibylline Oracles include: The High Priestess, Soothsayer and Evelina Caecilius Iucundus. (DW: The Fires of Pompeii)
