Dis, the Second Hell

The second circle of Hell, when described as its own layer, was a flat barren plane containing little more than black, stagnant rivers, stretching for thousands of miles until it reached some rolling hills. The sky was a cloudy dull green shot through with lightning. In the center of this plane rose the Iron City of Dis, several miles in height and hundreds of miles wide.[15] The foul rivers radiated from a moat big enough to be called a lake surrounding the Iron City.
