The amazing Invisible Sun Black Cube—one of the most astonishing and sought-after RPGs ever—is coming back into print!

This new expansion to Sentinels of the Multiverse explores the heroes, villains, and environments of the Multiverse — those who travel through it, those who have been touched by its vast impossibilities, and those who would seek to destroy it!

Make every encounter, adventure, and even campaign more engaging, memorable, and fun. From legendary D&D designer Monte Cook!
