Background[]
A chamber accessed through a portal near the Sylph's Fountain in the Dimension of Death. It is where the Sacred Heart is located. Connor found a Potion of Reveal near the heart. The floor was covered in organic blood and slime, and the walls appeared to be bleeding. When Connor fixed the problems in Dimension of Death, the heart began to beat again.
An engraving above the portal to the room, and on pedestal in the chamber read; "Heal me and save me from all vile, frightful, and red things."
Behind the scenes[]
The heart is likely based heart being judged in Egyptian mythology.
