Sewers, places where… well, you know. Everyone knows what goes there, and every city has them. When a city of this caliber and size was abandoned and became ruins, the sewers, well, they didn't go anywhere. They remained around, becoming worse over time, like an underground and labyrinthian swamp.
The once flowing water was now still, covered with green plants. The sun sneaked through various crevices and openings leading to the surface, and there were a lot of frogs, bugs, and rats everywhere.
And deep within this labyrinthian underground swamp, there was something, where all the water swirled together, a concentration of pure darkness.
It constantly spun around someone, or something, covered with green algae and mold, trapped within the swamp's vegetation.
From that, a black sludge constantly poured into the waters, contaminating them with strange and alien powers, forming something… different, and bizarre.
