The Beginning of the End
Acheron is an eternal battlefield of endless conflict. It is a plane of law where conformity takes precedence over any thoughts of good. Unending battles take place across the entire plane between huge armies, with no chance of victory or cease-fire. Each layer of the plane consists of a huge number of iron cubes of varying size, from continent-sized to small islands; not all of these are actually cube-shaped, but they are generally called cubes nonetheless. The cubes float in an air-filled, infinite space, occasionally colliding with each other.
Every cube face is habitable, with gravity always being directed towards the cube’s center; furthermore, the cubes are filled with caverns and tunnels.
The light on Acheron varies between that similar to bright moonlight to that of a dark and cloudy day. The sound of battle resonates around the plane and can always be heard in the distance.
The first layer of Acheron, Avalas, is also called The Battlefield. It contains the highest density of metal cubes and is thus host to the most fighting on the plane. The cubes are dotted with fortresses and covered with battlefields. Collisions between the cubes causes them to break apart in to smaller cubes, hence the smallest cubes are the oldest on the layer.
