Orophorkao

Orophorkao is a biological pit located near the Sulfuric Sea. It consists of a large pit, lined with the still living bio-mass of the species Caracal caracal. They survive by melding in this large pit, and satiate themselves by feeding on the nutrients and minerals in the nearby sulfuric water. Orophorkao is often used to dispose of bodies, or in ritual sacrifice.

Notably, Orophorkao appears to have a symbiotic relationship with Tenebrosus, and they possibly exchange sustenance. Which explains how such a biological anomaly can be sustained without being extirpated.
