This wide, deep laying basin is found at the foot of a steep ridge jutting out from the very southern end of the Croal Mountains. Stands of massive cedar and black locust trees, chocked with briars and hawthorns, makes for a thick barrier around most of the basin and creates a deal of hardship for anyone wishing to enter the deep pit of land. There are three narrow crevices within the outter walls that allow entry into the basin.
Within the basin itself, past the spike-ridden trees and bushes that surround it, there are no other plants growing within the area. This desolation is due to a concentrated band of salts and arsenolite that have slowly been leeching out of the surrounding rocks and poisoning the soil. The lowest section of the basin, a small niche on its southwestern edge, is immersed in a lifeless bog of water. The closest available drinking water comes from a fresh spring a few hundred yards outside of the basin, though it dose contain trace amounts of poisons within it.
With its high walls and the tall trees that surround it, much of the basin is shrowded in shadow, though towards the center there are basking areas where the sun comes through. Because of its sheltered location, and a lack of thermal activity in the area around it, the basin is generally cool during the summer, and very cold during the winter.
The Suporvestus Basin is widely believed to be a gateway to the afterlife, where others can come to remember past loved ones. It is often suggested that by sleeping in the basin, one's late family and friends might visit them in their dreams.
Since 2010, the Nuova Alba has taken up residence in the Suporvestus Basin.
