In the sky above London, a strange orb broke through the Earth's atmosphere. The only building in the vicinity happened to house the secretive Torchwood Institute, which immediately took possession of the ship.
As Torchwood began their tests, the ramifications of this event rippled through the multiverse. Tiny cracks in the walls between the worlds began to appear, and in the Vortex, the TARDIS saw what that meant. A year into the future was hardly a drop in the bucket for the ancient ship, and she could easily see two kinds of metal creatures bent on destroying the planet her human called home.
She saw her Time Lord trying to save them all, and she knew he would fail without help. The TARDIS scanned the universes for the perfect partners, and when she found them, she pushed herself through a crack to get to them.
