| Domain | Strength, War |
Acheron has four worlds, each a seemingly endless battlefield where the forces of gods and other powers are pitted in constant warfare. It is the system for lawful evil neutrals and home to a number of war gods. These Higher Powers have territory spread across one or more worlds, with boundaries always changing with the fortunes of war.
This system is a Domain for Strength and War. The Strength Domain gives the system's creatures a +5 enhancement bonus to their strength ability score. This extra strength only lasts as long as they remain in Acheron. The War Domain of Acheron is a much more complicated bonus that applies to battlefield situations. Two of the boons this focus provides to armies are a 1/- damage reduction and 100% increased recuperation from rest.
