Numenera / Arcana of the Ancients (Numenera material for 5E)

Arcana of the Ancients adapts Monte Cook's Numenera setting—science-fantasy set a billion years in the future—into D&D 5E-compatible content, offering setting lore, cypher-like artifacts, and conversion guidance.

The product was created by Monte Cook alongside veteran designers Bruce Cordell and Sean Reynolds to translate Numenera's themes into playable 5E material.

Shea cited it as a notable setting produced by designers with deep D&D experience and useful for groups seeking a different tone from traditional fantasy.

The book includes setting background, adventure seeds, and rules adaptations to capture Numenera's unique technology-as-magic flavor.
