Acheron (/ˈætʃɜːrʌn/ ÆTCH-ur-un)

The Infinite Battlefield of Acheron was an Outer Plane representing alignments between lawful evil and lawful neutral with emphasis on law.

Acheron is the home of dreams gone wrong.

— Wanderer of the Planes

The land masses on each layer were blocks of geometric simplicity the size of nations floating in a sea of air. The blocks would slowly collide and part without causing any upheaval or tremor, allowing beings to move to a new block if desired. The dance of the blocks was carefully orchestrated and creatures of high intelligence could usually discern a pattern for an area by studying the motions. It was said gravity pulled toward the center of the blocks but in practical terms gravity was normal to each surface.

Layers

Avalas - Battleplains

The blocks of the top plane were black with a metallic hardness that allowed the sounds of battle and troop movements to reverberate loudly. Avalas had the most block-like worlds and the highest population as the armies of the Outer Planes spent their afterlife clashing in neutral territory over differences both subtle and gross. The landscape consisted of cone-shaped mountains and pits plus the iron fortresses of the various armies.

Thuldanin

This layer was the scrap heap for countless contraptions, creations, weapons, armor, failed experiments, broken devices, fallen buildings, and shipwrecks of sea and air. The blocks of Thuldanin were hollow and pockmarked with pits that lead to the interior a few miles/kilometers down. There the flotsam and jetsam of the ages turned to stone in a matter of days or weeks due to the magic of this layer.

Tintibulus

The third layer of Acheron had blocks different than those of the other layers. Here the blocks were made of gray volcanic stone and the faces were six-sided, eight-sided, or even higher in number of edges. When the blocks of Tintibulus collided the surfaces would fracture along natural fault lines into hexagons great and small.

Ocanthus

The blocks of the fourth and final layer were square and so razor-thin as to be almost two-dimensional. They ranged in size from a few inches/centimeters to several miles/kilometers across. Both sides of the hard black squares had normal gravity pulling to the surface and could be walked upon. Being hit by the edge of one of these razor-sharp squares could be deadly.

Inhabitants

The main inhabitants of Acheron were the spirit legions occupying Avalas. They were made up of the spirits of humans, dwarves, halflings, orc, goblin and many other mindless soldiers who died in wars after forgetting their purpose; those for whom war became an end in itself. The spirits would congregate with others of similar beliefs or alignment and form nations on the surface of a block. They would fight to control a block and then join forces to conquer another block when it came within their reach.
