The Unfathomable Vaults of Thought

A player-driven depth-crawl through a dungeon of the mind. Written for Old-School Essentials and inspired by The Stygian Library. Submitted for The Appx. N Jam.

Long ago, the first wizard created a realm to explore the limits of magic and their own mind. Unearthed by a sandstorm, this realm manifests as a vast, shifting dungeon known as The Unfathomable Vaults of Thought. The first brave soul that entered found a space that formed itself around their memories and thoughts. They returned gravely injured but clutching a giant ruby. Since then, treasure seekers have braved the Vault but few return.
