[The 4th sublevel holds the worst criminals of the Lucullus Prison!] was what he read somewhere on a sign, so it meant that this one should be pretty empty, and the more they went up, the harder it would become.
The floor looked like it hadn't been vacuumed in months, and the air had a putrid smell that made his nostrils flare.
The walls were made out of purple obsidian, a strong material none of the participants could destroy, and the floor was made of white marble, debris were everywhere so it was pretty hard to navigate.
The hallways were pretty big, enough to fit at least a fifty people next to another, meaning that areas for battles were more than enough.
Also, each sublevel apparently had a name, and this one was… [The Domination's Layer].
Would the name be related to the floor and its enemies? Who knows.
