Abyssal Chasm

The sludge used by the Dreikathi forces on the mainland of Sapience is said to still be present on Albedos, north of a place called the Abyssal Chasm. Spellwards are erected there to keep the plague from spreading, but it also keeps wanderers from passing through it. At one time, the citizens of Delve knew how to bypass the wards, but that knowledge has since been lost.
