Background
At its core, the Blood War is ideological. Demons represent pure chaos and destruction, seeking to unravel reality itself. Devils embody strict order and ambition, desiring to build empires of suffering and control souls for eternity. This philosophical divide makes negotiation impossible; one side must dominate or be destroyed.
The conflict spills frequently onto the Material Plane, where mortals often become unwilling participants. Fiends recruit adventurers as proxies, offering boons in exchange for services that weaken their rivals. Planar portals serve as front lines, with armies of fiends clashing over control of these metaphysical gateways. Despite the constant attrition, neither side can be fully eradicated.
Demons are born from chaos and will always return to it, while Devils are formed from lawful evil souls ascending through the Nine Hells. This stalemate ensures that the Blood War remains a perpetual engine of conflict for gods, mortals, and monsters alike.
