It eventually gathers in the deepest reaches of the underground, where no ray of light can penetrate.
This corrupted wetland is known as the Aphotic Marsh.
Hidden within it lurks the mysterious being responsible for the corruption that has consumed the world.

They appear to have left someone behind before vanishing without a trace.
What is the connection between the Sorr, the Aphotic Marsh, and the source of the corruption?
Deep within the Aphotic Marsh, someone who has endured alone for ages, stripped of all strength, awaits Kisha.
Entrusting Kisha with the world's last hope, the mysterious figure grants Kisha the last of their remaining power.
Wield your newfound power and the Silver Chain, cut through the black corruption, and reach the deepest depths of the Aphotic Marsh.
