Preface

In 1908, a celestial body descended over the Siberian sky at an incredible speed.

But before it could crash to the ground, it exploded in mid-air, destroying 80 million trees in the Tunguska forest, scattering its mysterious composition across the region.

A little more than half a century passed, and the Tsar, the most powerful bomb in the world, initiated a genetic awakening right after its monstrous explosion.

Seventy years after the explosion, humanity encountered its worst enemy and suffered its greatest downfall.

Without technology, without resources, and with scarce food across the planet, the survivors of the human race hid in caves, tunnels, and small underground cities scattered around the world.
