The Keep (comic story)

Summary
An SOS summons the Doctor and Izzy to 51st-century Earth, which has been abandoned by the rich and powerful as the sun goes nova. Those left behind have fractured into millions of nation-states, warring through the ether in battles conducted via transmat. Only one place on Earth is safe from the wars -- the transmat-shielded Keep, the source of the SOS. Inside, the Doctor and Izzy find a prototype plasma sun called the Cauldron, created by the scientist Crivello. Crivello’s robot servant Marquez unexpectedly throws the Doctor into the Cauldron, but the Doctor emerges unscathed, having made a psychic link with the living sun. Crivello aged sixty years in six seconds when he tried to communicate with it, and Marquez thus summoned a time-traveller who could survive communion with the Cauldron and tell it what to do next. The Doctor instructs the Cauldron to launch itself into space, providing humanity with a new home in the Crab Nebula where they can await their eventual return to Earth. But as the Doctor and Izzy depart, Marquez snaps Crivello’s neck, and awaits the fulfilment of his true agenda...
