The Glimmering Valley gives you a fascinating and beautifully fleshed-out region from which to launch your Numenera campaign. It details an area of the Ninth World made specifically to be the origin point of a group of eager explorers. It brings Numenera back to its roots and gives players a place to call home. A place to defend if and when it becomes threatened - and a springboard into the many splendors and dimensions of the broader Ninth World setting.
