After centuries believing that he was the last Timelord. That he had destroyed Gallifrey to end the war; he now knew that he hadn’t. He had saved them, all of them. It had taken all thirteen of him to manage it. But, he’d done it. He’d saved them.
And then, with the knowledge that he will forget all about the last couple of days, because it always seemed to work like that when more of him came together. The Tenth Doctor detected an anomaly in London. A rift in time and space, a rift that started bringing people from other times, and other places; other worlds and dimensions. A rift that stopped the TARDIS from travelling in time. Stuck on the slow path, the Doctor must try to protect Earth from the threats that come through the rift. But, he won’t be working alone.
