I used to be the greatest Earth Mage in my world. The head of the entire Order of Architects. But the older you get, the more you come to realize that at some point, you need to retire, so that you can have the chance to enjoy a peaceful life and to cede your place to the young, some of whom have already turned two thousand years old . . .So that's what I did. But I failed to account for one thing: during the course of my long life, I'd accumulated too many enemies, and they had decided to spoil my retirement. So they died along with me. And I hope their deaths were final. But mine was not!

None of this mattered much to Derek, aside from making living a little more perilous.

Greg walked into a bar hoping to wash away the sour taste of a bad day at work. What he got instead was a bartender offering him the opportunity of his dreams—with a catch.

Maxwell Carter works a maintenance job at a government research facility. The research lab he works at has an accident, more energy coming through the wormhole than anticipated, enough to completely rupture the shields that were supposed to contain it until they finished determining how to convert the energy into electricity.

But he has a certain set of skills that catches the attention of the Daemon System as it implements a secret beta-test on Earth.

Planet Earth burns in nuclear flame. But The System was kind and wise enough to transfer all its little humans into a new world. Everyone has been granted a new name, a starting bonus, and a rousing kick up the backside. Some got a sword, some a crown, and me . . . A potato?! How am I supposed to take over the world with this thing? System, are you sure you're so kind and wise after all?
