The Hapes Cluster was a grouping of several hundred stars within the area of nebulous gases known as the Transitory Mists within the Inner Rim—an impediment to hyperspace navigation that had kept the stars of the cluster isolated from the rest of the galaxy from before 3,000 BBY. This region's high density of stars, nebulae and moons bathed its worlds—particularly Hapes itself—in bright light, which, over the centuries, caused the Hapans to lose most of their night vision.
