Underswamp

The Underswamp is an area of the Stygian Abyss. It was the $650,000 crowd-funding stretch goal that was unlocked during the Kickstarter campaign on 1 March 2015.

Background
Crouched on the confluence of two slow-moving subterranean river systems, the Underswamp is a miasma of odd fungus, twisted trees and creeping lichen. Dank and full of life; a menagerie of deadly toothed and venomous predators roam the spongy terrain. But there is also strange beauty to be found, such as shimmering fluorescent air plants floating above the dark waters. Deep within the Underswamp lie ruins of the temple of Ishtass. This extensive complex, nearly a league across and half sunk in the swamp, is said to hold ancient secrets.
