Fiction:The Firmament/Fire Pits

The Fire Pits are the region of Irkalla belonging to the demon lord of war and destruction, Druacath.

Description
The Fire Pits take the form of a great ravine which burns in hellfire. Demons and mortal slaves toil day and night creating weapons and armor for the Lord of Brimstone's armies, so he may wage terrible campaigns across the cosmos. The demon lord himself typically rests in his great throne, flanked by the corpses of those slain in his name, until he grows bored and decides to spar with his greatest generals, to the chagrin of anyone unfortunate enough to be caught in their path.

Inhabitants
The Fire Pits are inhabited by many demons, who take joy in making damned souls toil away at the ore mines. Lesser demons are equally unfortunate here, enslaved if they do not manage to rise in the ranks of Druacath's army. Evil Greenskins such as orcs and goblins are sent to this realm to be turned into either soldiers or slaves.
