First Day of the Doctor (short story)

First Day of the Doctor was a short story exclusively published in Doctor Who The Official Annual 2024 on 7 September 2023 by Penguin Group. The short story, stylised as diary entries written by a selection of Doctors after their first adventures, was notable for the first work of fiction released to feature the Fiftheenth Doctor and Ruby Sunday.

The Seventh Doctor
The Seventh Doctor writes that he was in the middle of a spin class set up by his friend Mel when the TARDIS was forced to land on the planet Lakertya, causing him to regenerate after the crash landing. His assailant was the Rani, an old schoolmate of his, who had gone "rogue" and was trying to feed geniuses into a giant brain as part of some "preposterous plan" to achieve time manipulation on a large scale while he set about to stop her. The Doctor concludes, needn't specifying the outcome, as it was to him, obvious.
