Abyss Pit
A disease that killed 80% of the population, human evolution, alien constructs that came from the sky, and tens of thousands of Abyssal Pits that suddenly opened all over the world. All these unreal things made Viktor wonder if he truly only stayed inside the bunker for two years and did not exit into a different world instead.
What stood before him right now was a broken stone gate standing about ten meters tall. Viktor have heard about this before and knew a little about these Abyssal Pits that began appearing roughly six months ago, releasing numerous different abyss creatures to the world.
They had not taken a step past the gate, yet Viktor could feel a strange heat emitted from whatever was inside. The heat could not be considered unbearable as it was only slightly hotter than warm, but it gave him a sense of discomfort.
