The Doctor thought he had defeated the microscopic Nucleus of the Swarm in his fourth incarnation. He was wrong. It survived within the TARDIS, and now it has been brought back to Titan Base, to the point of its own creation. It has a plan that spans centuries, a plan which will result in the Nucleus becoming more powerful - and larger - than ever before.
