Cassandra (The Myth Makers)

Cassandra was the High Priestess of Troy and the daughter of King Priam, whom The First Doctor's companion Katarina served as handmaiden. She was the sister of Paris, Hector and Troilus.

Biography
For a time prior to the arrival of the Doctor's TARDIS, Cassandra had had nightmares of the future. A mean-spirited and vindictive sort, she nevertheless warned Priam and those associated with her that doom would come to Troy, the people of which had long failed to take her seriously. When Vicki Pallister, later called Cressida, emerged from the TARDIS, which the Trojans had taken to the city, Cassandra immediately accused her of practising witchcraft. She warned of the Trojan Horse, a plan put into action by the First Doctor, borrowing the idea from Homer, but to no avail.

After the fall of Troy, in which her father and her brother Paris were killed, she became the slave of the Greek warlord Agamemnon. (TV: The Myth Makers)

Cassandra chose Katarina as her handmaiden as she predicted that she would die. (PROSE: Scribbles in Chalk)

In 1963, Susan Foreman recalled in her diary that Cassandra was kicked to death for being able to see the future. (PROSE: Time and Relative)

Cassandra was resurrected in the City of the Saved as a young woman. In AF 291, while on the Tube, Cassandra prophesied in painstaking detail the imminent Civil War. (PROSE: Prologue to Of the City of the Saved...)
