100 Unusual Demiplanes
A collection of alternate dimensions, each limited in size and shaped by unusual properties. These demiplanes may have been created as sanctuaries, for specific purposes, or by unknown powers, and can persist long after their creators are gone. Each demiplane is linked to another plane or demiplane and may be discovered by explorers seeking refuge, investigating an alien environment, or uncovering the purpose behind its creation.
