The misadventures of Ssarok, an alien warlord on Earth

Ssarok, a violent warlord, conquered his own planet, Vexria, a world where might makes right. He was bored after becoming the ruler and literally seeking a new world to conquer, he traveled to Earth, a planet previously visited by one of his ancestors, who'd returned with a a copy of "The Complete Works of William Shakespeare." Ssarok, fascinated with the Bard, looked forward to thigh adventure on Earth, however the world had changed since the days of Shakespeare.
Instead of Lords and Ladies, Ssarok found a world filled with fragmented governments, crime, television, social media, protests, vigilantes, and lawyers. Lots of lawyers. And rules, lots of rules thar Ssarok didn't know or understand. What's a vicious warlord got to do to survive? Well, for one thing, he needs a good dog and time to learn how to use the rules to his advantage.
