Doctor Who fan fiction.
An extremely short piece, this takes place inside the Fifth Doctor's mind at the end of the 1984 serial 'The Caves of Androzani'. That serial ended with both the Doctor and his companion Peri contracting spectrox toxaemia, and the Doctor only managing to secure enough antidote to cure Peri, forcing him to undergo a traumatic regeneration. Paliatseas's story imagines the Doctor's thought processes as he prepares to save Peri at the cost of his own life, including an internal dialogue with the Doctor's long-term enemy, the Master.
