This continent is doomed. Slowly but steadily, it is swallowed up by the Black Forest: a gloomy thicket inhabited by the undead, where even the leaves of the trees are black and lifeless. No one risks going there. None but gamekeepers: aliens from our world whose abilities evolve as the undead are killed. For locals, it looks like magic. For us, gamekeepers - like a computer game. Except this game doesn't have an Exit button. I wanted to just test her, but now I was stuck in her world of steel and gunpowder, not knowing where sleep was and where reality was. Are I surrounded by real people or playable characters? And does the game have a final, or is that my life now?
