Mira (The Fires of Pompeii)

Soothsayer is a member of the Sibylline Sisterhood that were in Pompeii in 79 CE. She has eyes painted on the back of her hands - a sign of a soothsayer. She was the first of the Sisterhood to see the TARDIS or "Blue Box" that had appeared in a prophecy. She had psychic powers due to breathing in dust from Vesuvius that was converting her into a Pyrovile and could see time thanks to the rift activity there. It is likely that she died during the eruption as it has not been shown otherwise. (DW: The Fires of Pompeii)
