Louisa Keldafrian
From Tardis Wiki, the free Doctor Who reference
Louisa Keldafrian was a princess who had fought the spiders in over 50 campaigns. She questioned the Seventh Doctor about why he was in her palace. She also danced with him and gave him a rose.
Henry wove a time loop around Louisa 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)
