Mistress Ellen

Mistress Ellen was a maid for Queen Jane during her nine-day reign in 1553. When Rani Chandra was sent back to 1553 to acquire a piece of Chronosteel, Ellen assumed Rani to be the queen's new Lady in Waiting. She gave Rani a dress and led her to the queen. She learned that Mary I of England had claimed the throne and thus Jane was a traitor and would be sentenced to death. Lady Matilda tried to kill Jane that night but Rani stopped her. Matilda wanted to kill Jane so she would become a martyr. Rani worked out that the dagger Matilda tried to kill Jane with was the object the Shopkeeper was after. She retrieved it and stayed to comfort Jane before using it to teleport back to 2010. Ellen suspected that Rani was a witch but Jane suspected Rani was an angel and this strengthened her.
