The Nine Layers of Hell

"So for a start, and before you start telling me it's a dangerous idea. Let me explain what hell is to you." Cain started describing hell and why it's useful.

Hell is composed of nine layers, ranked from the upper to the lower. The upper layer, also called the first layer is named Avernus. The first circle of Hell was also the "topmost" because Astral travelers would emerge from color pools (Like the Gate Cain got) on this layer and reaching the next circle required descending to the lower depths to breach a barrier to Dis.

The layer is a wasteland of erupting volcanos, acid lakes, and rain. Just the air alone causes extreme irritation because of the massive amount of acidic vapor and toxic chemicals from the volcanos.
