Shaya Costallion was the leader of the military unit that was sent to Midnight to find out why the miners on the planet had disappeared. She had joined the military because of a war that happened on her homeworld during her childhood and had become highly sufficient at pistol shooting because of it. She tried to learn more about the situation after meeting Aliss Fenly but was relieved of her command by Cassio Palin-Paleen because of her perceived incompetence.
After Cassio was killed by the Midnight entity, she resumed command and listened to the Fifteenth Doctor’s commands about how to stop the creature. She shot at the mercury pipes to create a mirror to allow the creature to see itself. Upon trying to escape the base, she asked if the human race’s biology was similar to her own race, so that she could shoot Belinda Chandra so that the entity would attach to her. She then committed suicide by jumping down the mineshaft, hoping to trap the creature. (The Well)
