Grace Lord
From Tardis Wiki, the free Doctor Who reference
Grace Lord was a Silostophan who, along with many of her people, was enslaved by the Christmas Corporation to work as elves. They were kept drugged so they would obey the managing director, S. Claus. The Fourth Doctor and Adric met Grace when they were captured by Mr Claus. She helped them start a rebellion of the slaves. (PROSE: Planet of the Elves)
