Perfect Victim
From Tardis Wiki, the free Doctor Who reference
The Perfect Victim was, at the age of eighteen, (PROSE: The Aztecs) the Aztec human sacrifice intended for Tlaloc, the Aztec god of rain, when the solar eclipse came. Susan Foreman refused to marry the victim and was sent to be punished. As Susan escaped capture, the sacrifice occurred as scheduled. (TV: The Aztecs)
