The stars moved randomly such that all attempts to map them into constellations were unsuccessful. Above any clouds or fog that might exist in a region was a clear night sky full of wandering stars. The bottommost layer was the land of starlight. Some speculated that the wilderness and life-giving properties of the plane were sufficient to root the tree there.

The reason was unclear, since there were no realms of the Norse pantheon anywhere in the plane. Yggdrasil, the World Ash, extended its branches to all layers of the Beastlands. Any attempt to control the winds, weather, or atmosphere was countered by those airborne creatures who lived in the region. Weather in one region did not affect adjacent regions, so an arid desert could exist next to a snowy winter region for example. Weather was regionally distributed and provided all manner of conditions for the habitats of all creatures. Each layer had its own time of day which never varied. The Beastlands had three layers, all heavily forested with normal and giant trees, plants, moss, and fungi. All natural creatures and their giant versions from the Prime Material Plane, including mammals, birds, fish, reptiles, amphibians, insects, and invertebrates, excluding enchanted creatures and monsters, were represented here, and they called their home the Beastlands. Some of the most intelligent creatures could even wield magic. But the native inhabitants of this plane were all capable of speech and comparable to humans in range of intelligence. The name Happy Hunting Grounds was given to this plane by those that first scried it, assuming the abundant and varied game and wildlife would be a sportsman's paradise.
