Astropolis Series by Sean Williams

In the forty-third millennium of human history, Imre Bergamasc awakens after two hundred years to the realization that he has been the victim of an elaborate murder plot-a plot that also destroyed the intergalactic transport milieu known as the Continuum. But now that Imre has been reborn, he will stop at nothing to help bring forth the rebirth of the galaxy.

In the far future, in the aftermath of a mysterious galactic catastrophe, a false prophet comes face to face with his greatest adversary yet: a man who thinks he's god, and might very well be right. While the battle for Earth rages around them, they face off, one wanting to conquer the world and the other to redeem it.

Imre Bergamasc is the First Prime of the Returned Continuum, ruling Earth and the far-flung regions of the galaxy. But dissidents and saboteurs threaten to bring his reign to an end.

Six hundred thousand years after Imre Bergamasc's abdication, the Host rules the supposedly peaceful galaxy. But revolution is fomenting-and Imre's unexpected return may be all it takes to light the final fuse.
