Ashildr

Ashildr (also known as Me) is a fictional character in the British science fiction television series Doctor Who, portrayed by actress Maisie Williams. The character was introduced in the ninth series episode "The Girl Who Died", before making a few more appearances during the series.

==Appearances== Ashildr, daughter of Ionhar (Ian Conningham), is introduced in "The Girl Who Died" (2015), where she is portrayed as a Viking puppet maker and storyteller. When the militaristic alien race the Mire raid her village, Ashildr declares war between the village and ten of the Mire. As part of a battle plan devised by the alien time traveller the Twelfth Doctor (Peter Capaldi), Ashildr uses the technology inside one of the Mire's helmets to create an illusion to scare the Mire into a retreat. In doing so, she dies of heart failure, having been "used... up like a battery" by being connected to the Mire's machine. The Doctor's companion, Clara Oswald (Jenna Coleman), a time-travelling school teacher from 21st century England, persuades the Doctor to save her. He implants Ashildr with a Mire repair kit, bringing her back to life and making her functionally immortal, but he worries that there will be consequences and no companion for the immortal. He also gives her another piece of the same technology that brought her back to life before leaving.
