Biography
Shireen was a student of St Luke's University in 2017. She was a good friend of Bill Potts and had met the Twelfth Doctor at his lectures. She and a few other students began looking for students accommodations. After an afternoon of disappointing offers from an estate agency, they were approached by a Landlord named John who offered them his house for a cheap rent price.

The following evening, everyone moved in. Shireen began to notice strange noises coming from inside the walls and noted Pavel's apparent absence. Once everyone had eaten, Bill and Shireen followed Paul upstairs only to hear alarming noises coming from his room. The house then seemed to come to life around them and sealed itself shut.

Bill and Shireen then went into Pavel's room and found him partially absorbed into a wall, much to Shireen's horror. Before they could help him, John appeared and stopped the music, causing the wood to absorb Pavel completely. They ran away as John began summoning the Dryads to kill them and made their way into the tower. Shireen and Bill then met Eliza whose body had been turned into a wooden like substance to preserve her from death.
