«The Chronomancer’s Burden» is a novel by Vladimir Myasoedov, the fifth book of the eponymous series, in the LitRPG and RealRPG genres.
The hero’s terrible dreams came true, and people returned to the planet Earth. Those who could not be broken by any obstacles, who managed to adapt, who were lucky enough to develop their classes and reach those coveted levels… Only, their old home is gone, because the familiar world has changed beyond recognition: everything has changed—climate, fauna, flora, the outlines of the continents… And it is populated now not only by people. And the people who are there at all do not always come from this planet. And anyone—anyone—at all, but Balthazar especially knows that the race for survival hasn’t ended; it has simply moved on to the next stage. It’s a shame he can’t share this knowledge with everyone around him, splitting the weight of the Chronomancer’s burden…
But he can do plenty of other things, because he knows the future, has a real flying city at his disposal, and commands an entire army—just as befits a legendary warlord.
