Acheron comprises four realms, each an unending field of battle where the forces of deities and other mighty entities engage in ceaseless conflict. It is the domain of lawful evil neutrals and the abode of numerous war gods. These Exalted Powers possess territory spanning one or more realms, with borders perpetually shifting alongside the tides of war.
This system is a domain focused on strength and warfare. The Strength Domain grants the system's creatures a +5 enhancement bonus to their strength ability score, though this extra strength only persists as long as they remain in Acheron. The War Domain of Acheron provides a more intricate array of boons applicable to battlefield scenarios. Two such boons are a 1/- damage reduction and a 100% increase in recuperation from rest for armies.
