This module is two books in one publication: "Cavern of the Purple-People Eaters" is a first-level adventure for PCs finishing their funnel adventures. "What the Hex" is a complete purple planet setting area with low-level adaptations of encounters, creatures, situations, plot hooks, and artifacts. Just as violet is a lighter shade of purple, "Random Acts of Violet" content represents risks that are (a little) less than the full force of what the purple planet has to offer.
