Spirac

Spirac was the 71 layer of the Abyss. It was an uncivilized place with no ruler.

Description
Spirac was a wild land of deep forests of spiky ferns and thin, towering mountains. It was impossible to build anything on the layer, and all attempts crumbled into weed-covered ruins and then natural rock within months of their creation.

Notable Locations
A mountain pool located near the presumed geographical center of the layer was said rejuvenate 10-40 years for any mortal who bathed in it.

Inhabitants
Spirac was home to a staggering variety of of unusual animals and magical beasts. Many demon lords used Spirac as their personal hunting grounds, and would take offense when they ran into any "intruders"; despite this, hunters flocked to the layer to hunt yeth hounds, vorrs, nightmare beasts, and much worse. Cannier hunters would bring lesser demons such as abyssal skulkers and jariliths to aid them.

Additional, many mortals came to the layer, drawn by the legends of the rejuvenating pool that lay at its center, although most ended up as prey in the bags of hunting fiends. However, those who reached the pool, supposedly, had to sacrifice a portion of their free will to the demon lord Soneillon, called the Youthful Crone, who lived within its depths.

History
Long ago, as the obyriths fell and the tanar'ri rose in power, an alliance of seven demon lords hunted the obyrith lord called the Malgoth on the fields of Spirac. In much more recent times, the demon lord Mastiphal won Malcanthet's favor by presenting her with the head of a huge fiendish smilodon that he killed in Spirac.
