This was the abyss, the horrid and ever-growing cesspit hole where demons are born and where they live. The deeper you go, the viler and degenerate the demons get. While devils are lawful evil, making sure to keep at least a modest amount of order in their ranks, the demons are chaotic evil, nothing is off limits to their corrupted souls.
The mere sight of a demon in Alaric's layer is enough to drive a man into insanity. Large furry beasts, the ancient wounds of their battle have rotten and are now serving as the bed of countless maggots. Day in and day out, they live by murder and violence. Killing each other is as common as speaking is common for humans, and for the poor souls that end in the abyss, it might be a fate worse than hell itself.
Arad is the kind, but still a terrfying dragon.
