The world has ended.

In its place is a world flattened and broken, where time has been displaced and darkness perpetually blankets the sky. Horrors crawl through the streets. People hide in fear. At the Centre of the World, an ancient city is being reconstructed, and once complete, an unspeakable evil from outside of Time will have the means to bring to fruition its unholy plan to reshape the universe.

The Doctor and Christine must find a way to stop this from happening. With the help of a young woman named Moira Skye and a disturbed man named Trent, they must make their way across the shattered world to confront a mad god and his minions.

But even if they make it past the Museum of Lies, survive the Hounds of a certain ancient Greek hunter, and cross the near-infinite wastes, how will they defeat a being with the power to destroy a universe?
