The Beastlands are an Outer Plane in the AD&D Planescape setting, lying between Elysium and Arborea, and thus representing Chaotic Neutral Good alignments. The plane has three layers:

Krigala, the land of eternal day.
Brux, the land of eternal twilight.
Karasuthra, the land of eternal night.

All these layers seem wild and untrammeled, a kind of ideal natural state. However, it is not ideal, but idealised. This is nature as perceived by people. Nature itself is amoral and unaligned.
