A cold dark evening. Abel walks through the snow-covered streets, a strong blizzard hits him in the face.

He doesn't understand what's going on. The last thing he remembers is how he returned from the academy and how his mother promised to cure him and Cain, his younger brother. And now Abel has just got out of the hydro chamber, he is on earth, there are no people or immortals nearby, the world is extinct.

Abel spread his snow-white wings and tried to fly, but nothing happened. He couldn't even lift his body into the air for a moment. Cursing softly, Abel looked down at his bare feet, which were covered with snow. He clicked his tongue. Cold.

After taking a few breaths, he wandered on, but the blizzard kept knocking him down. When Abel got up from his knees for the fourth time, he heard some strange noises, felt inhuman energy and a sepulchral cold.

When he stopped, he turned around and saw the demonic spawn, and behind them were infected people.

Abel bit his lip, remembering that he had studied them in demonology during the academy. The angel tried to concentrate his power while they surrounded him. But nothing came out, he was weak and powerless. There was nowhere to run, the brats surrounded him with a dense wall. It was impossible to take off, and the man closed his eyes, preparing for death.

At that moment, he heard strange noises, and then the roar of the brats. Opening his eyes, he saw a girl clearing the way for Abel. She gave a sign and he ran after her, but he couldn't understand: why would human save him?...
