Alison Keldafrian
From Tardis Wiki, the free Doctor Who reference
Alison Keldafrian was a princess. She often took soldiers as love interests, but was paranoid that they preferred her sister Louisa Keldafrian. She later talked to the Seventh Doctor about the spiders. Henry wove a time loop around Alison and her sister in an attempt to make them turn on each other, and so prevent them working together to fight his advancing forces. (AUDIO: Spider's Shadow)
