In the alternate timeline where Sombra was not stopped, a human finds himself suddenly in Sombra's body... just after the dread tyrant has conquered Equestria. Now trapped in a world where just about everyone hates him, he must try to keep up the illusion that he is the villainous conqueror, while at the same time try to win over his new subjects.
However, this will not be so simple, as the real Sombra is not quite dead... and he is most definitely not happy.
