The Underworld

The Underworld is a small plane, but too big to be called a pocket or demi-plane. The Underworld was split off from Avernus in The Nine Hells near the beginning of The Scouring to contain an extremely powerful entity.
Souls that are lost on the golden path of the Fields of Sorrow in the Shadowfell are pulled into this realm for unknown reasons. There have also been several dead adventurers who have been chosen by their deities to explore this unknown plane, including Cicada Yue.
The lands of the Underworld are constantly patrolled by Devils, Demons, Fire Elementals, and Fallen Celestials.

Geography

Much of this plane is unknown.
To the south are massive expansive lands that stretch out, that have been torn apart and put back together. What must of been at one point flat plains, is now cracked jagged ground with the larger of the strutting ground forming large hills.
To the north is a massive range of volcanoes that are constantly erupting, filling the Underworld sky with burning clouds of fire.
North beyond the volcanoes is unknown, but those who visit feel compelled to find out.

Climate

It is very hot and very dry in the Underworld. The closest thing there is to rain is when ash and fire fall from the skies.
