Star Emperor from a Rental Room

On Earth, he's just another broke shut-in scraping by in a cramped rental. But across the stars, he reigns as His Imperial Majesty—Emperor of the Eternal Empire, Conqueror of a Trillion Stars, Master of a Thousand Worlds. Technological juggernauts, psionic collectives, immortal cultivators, demonic hordes, zerg swarms, and holy crusaders... every civilization, every world, will kneel before the Emperor's absolute dominion. From his humble room, he commands fleets that shatter planets and legions that reshape galaxies. The universe has no idea who's really pulling the strings.
