Fiction:The Firmament/Pit of K'tharn

"I gazed at the Pit of K'tharn. It gazed back at me."

- Jehenne Dawnhelm, Aynachian wizard, declared insane

The Pit of K'tharn is a demiplane within the Ethereal Plane which serves as the lair of the dreaded god of aberrations, Xhuulthanol.

Description
Very little is known of the Pit of K'tharn, for those who venture there rarely return. It is known for being a realm shrouded in darkness and made up of broken pieces of landscape surrounding the namesake pit, which devours all like shined upon it. Many claim the chunks of land which surround the Pit of K'tharn are fragments of worlds destroyed by the Faceless One during forgotten eons of history.

Inhabitants
It is believed that those who deliver their souls to Xhuulthanol in life are sometimes claimed by the Pit in death, where they are transformed into eldritch horrors which serve the whims of the destructive deity.
