Biography

Declaring war

Ashildr greeted a group of Viking warriors when they returned from their journey with the Doctor and Clara in chains. Soon after their arrival, a figure claiming to be Odin appeared in the sky and invited the warriors to join him in "Valhalla".

Having been given half of the Doctor's sonic sunglasses by one of the warriors, she was also taken to the Mire spaceship when undoing Clara's chains.

Unable to save the warriors, who were killed for their testosterone and adrenalin, Ashildr confronted "Odin" to the point of declaring war on the Mire. She and Clara were returned to the village, where they were given one day to prepare for the Mire's return. (TV: The Girl Who Died)

Becoming immortal

When the Mire attacked, Ashildr was an integral part of the Doctor's plan to save the village, donning a Mire helmet and using her imagination to send false signals to the rest of the Mire, who viewed their surroundings via holograms. When "attacked" by a wooden dragon, the Mire believed the dragon to be real, and retreated when the Doctor threatened to share the footage, ruining their reputation.

Ashildr was killed in the process, but was resurrected by the Doctor altering a Mire medical kit to fix human physiology. He left another for her to give to whomever she chose, knowing that she would continually be fixed, thus losing the "ability" to die. The Doctor later realised that she was a human-Mire hybrid.
