Acheron

From Ardrana

Here's the safest place for a cutter to go if he really wants to deal with the fiends of the Lower Planes - the iron-shod Acheron. It's a plane of enforced order, where conformity is more important than good. The Mercykillers will tell a berk that the fiends of Acheron aren't that evil - it's only their rigorous adherence to order that upsets those who lack such discipline. Other folks tell of the random cruelty that blind conformity brings - the crushed spirits, the broken hopes. This is the true face of Acheron.

The plane of Acheron is made of immense blocks, black and smooth, whose surfaces ring metallic underfoot. They drift endlessly through space, these cubes the size of cities and kingdoms. Sometimes they meet with a fearsome clang that crushes all between them and sends shudders through the plane.

The petitioners of Acheron, warriors lost to the joy of battle and saviors who forgot their cause, are consumed by the need for conformity. They cannot conceive of anyone refusing to obey the will of the group, as determined by their commanders. They are dedicated soldiers, forever lacking a cause.

Along the Great Road, Acheron is between Baator and Mechanus.

Note: Acheron originally appeared in the Planescape AD&D campaign setting from TSR. Its use here is for the purposes of providing context for the campaign only.
