Plot
Lev is no stranger to the evils of the world, having spent a lifetime fighting the predatory system that ensnared the world's population and turned them into puppets for the leaders of humanity. But after being assassinated, he finds himself in a new world—one with different yet familiar evils.

It's a similar road he must traverse, but this time he can do so with a lifetime of experience behind him.
