Acheron was an Outer Plane in the Great Wheel cosmology model representing alignments between lawful evil and lawful neutral. Some characteristics of this plane were ascribed to the World Tree cosmology planes of Clangor, Nishrek, and Warrior's Rest when that cosmology became popular. Nishrek and Warrior's Rest survived the Spellplague and became part of the World Axis cosmology model.
