This story is a sequel to On the Fields of Trenzalore

The Doctor crash-lands on Karn, a planet he hoped he would never have to return to. There, he meets One Direction, who give him the power to end the Last Great Time War.

Meanwhile, on Gallifrey, the war threatens to destroy all creation.

Meanwhile again, the previously dead Doctor recruits Twilight Sparkle and himself in the fight against himself.
