Chapter 17: Donjon - The Book of Many Things

Chapter 17: Donjon. This chapter, intended for DMs, details a dungeon called the Donjon Sphere. You can use this dungeon to describe the fate of a character who draws the Donjon card from a Deck of Many Things. This chapter also includes suggestions for other ways adventurers might end up in the Donjon Sphere, as well as advice for how to continue a campaign or keep it on track if the party gets split up. The Donjon Sphere The Donjon Sphere is a metal sphere that drifts through the Astral Sea. Centuries ago, an unknown species of intelligent beings built the sphere to capture and contain specimens from across the cosmos. They used strange magic to peer into the minds of their captives and observe them in simulated environments, curious to understand the minds of these alien creatures. When the first Deck of Many Things was created, the Donjon card was linked to the sphere, sending prisoners there. The collective distress of the sphere's prisoners ultimately attracted the attention of a group of Feyr: Astral Sea monsters that feed on creatures' nightmares. The feyrs infiltrated the Donjon Sphere and wrought havoc, forcing the sphere's stewards to abandon it. After devouring the nightmares of everyone left inside the sphere, the feyrs moved on. Since then, the Donjon Sphere has drifted through the Astral Sea. Automated systems keep the vessel working and on course, and Constructs called detention drones bring in a steady supply of fresh specimens. However, swaths of the sphere have fallen into disrepair or outright mayhem. For new arrivals, many brought by a Deck of Many Things, the anarchy means it's never been easier to wriggle free of the dungeon's crumbling wards and traps. However, this same chaos still makes banishment to the sphere extremely perilous. Finding the Sphere The Donjon Sphere is too small to be observed from any planet's surface without a telescope or magical aid, but clues to the sphere's whereabouts can still be found among the stars.
