Eberron: Scales of War
On the outer fringe of Khorvaire both physically and socially The Demon Wastes is a forbidden realm of barren rock, the last remnant of the ancient civilization of rakshasas that reigned over Khorvaire before the Age of Monsters and long before humans ever stepped foot on Khorvaire’s soil.
North of the Eldeen Reaches beyond the Shadowcrag and Icehorn Mountains lies the scarred land of the Demon Wastes. Hanging like a scab on the edge of Khorvaire many in Khorvaire would sooner forget about its presence than acknowledge its existence, or what calls it home. Many hope the land would slough off into the Barren or Bitter Sea or perhaps float north and join the Frostfell freezing whatever foul denizens call the place home in a permanent glacier.
There is no overarching society amongst the Demon Wastes. The few settlements that lay in the borders of the Demon Wastes are unique and rarely contact the outside world. The most prevalent social groups in the Demon Wastes are the nomadic barbarian tribes. There are two separate groups the Carrion Tribes and the Ghaash’kala. While the Carrion Tribes worship the imprisoned rajahs the orcs of the Ghaash’kala have sworn to prevent evil from escaping the Demon Wastes. In Ashtakala the Lords of Dust hatch their insidious plots while Night Hags content themselves with small groups of devout followers. Despite the varied powers in control across the Demon Wastes there is one consistency, the preponderance of evil.
In the great and forgotten Age of Dragons the three progenitor dragons formed the world that we know today. Khyber imprisoned in the coils of Eberron spawned unimaginable horrors called fiends which surged to the surface world through cracks and volcanic eruptions. At that time dragons as we know them, were a shadow of their current power. Fiends overran the world and the Age of Demons began. Powerful rakshasas, zakyas and night hags reigned over the world for thousands of years.
Though it is not known how, what is known is that the dragons rediscovered the Draconic Prophecy which reminded them of their heritage and great power. Spurned by the new revelation the dragons launched all-out-war against the fiends of Khyber. The end of the war came, but at a great expense. The greatest of the fiends could not be destroyed, they could only be bound by the sacrifice of the couatls who imprisoned the powerful fiends in the depths of the Dragon Below. The lesser fiends who were not destroyed escaped to the region known as Fah’lrg or the Demon Wastes in Infernal. It is here that the fiends formed the Lords of Dust vowing the release and restore the imprisoned rajahs.
Little attention has been paid to the Demon Wastes over time and the Kingdom of Galifar was no different. Though Galifar I claimed his kingdom spanned the length and breadth of Khorvaire his holdings at the rim of the continent were tenuous at best and the Demon Wastes especially saw the least effort of reclamation. In fact the region of the Demon Wastes is the only region of Khorvaire not included in the oldest lasting maps of the original Five Nations as if by simply ignoring its presence the region might disappear. The attitude, it would seem, has carried on to the people of Khorvaire as well to the present day.
