Underworld

The Underworld is one of the prime planes, believed to be the most cursed place in the known universe. Many cultures refer to the Underworld in myth and legend, with the realm taking on characteristics of each of these beliefs. Any culture with a concept of hell will have it reflected here.

The Orange Guardian was imprisoned here, causing it to become corrupted and evil as a result of the realm's malicious influence. Forrest, the keeper of the Orange Guardian often draws his minions from the Underworld to wreak havoc across the West Coast and beyond

One of the largest portals to the Underworld lies beneath Marrowstone Island.
