Editing Blood War (section)

==In Pathfinder==
Perhaps because the Blood War isn't OGL-covered, [[Pathfinder]] makes no use of it. Demons and devils fight, yeah, but that's because they're ''evil, destructive bastards'' who sometimes get in each other's way. There's no big philosophical fight between the two. Indeed, as demons in Pathfinder are created from mortal sins, and devils live to corrupt mortals by committing sins, one can say that devils literally ''create'' demons.

This does not explain why, since the demons have vastly larger numbers than devils, same as in D&D if not more-so (The Great Beyond cosmology doesn't go into the whole 'balance' thing), they didn't destroy much of Golarion and the Prime Material Plane already, given how none of the Celestial races focuses on directly opposing them, though local gods are known to. In fact, demons and devils so rarely come up against each other in Pathfinder Adventures/Modules, that it often feels like Paizo is trying their darnedest to not even hint at there being something similar to the Blood War in their universe, and get sued by WOTC. 

That said, there are three big fiendish conflicts in Pathfinder.

Firstly, the Abyss was originally home to a fiendish race called the Qlippoth (your basic Lovecraftian "this thing should not exist" monstrosities, also Chaotic Evil - expect tentacles), who are very peeved about how mortal sins caused demons to arise. To this end, they want to annihilate all demons ''and'' all mortals, to stop any new demons from being born.

Secondly, Daemons - Pathfinder's equivalent of Yugoloths, the "Neutral Evil fiends" - are characterised as omnicidal maniacs. They want to annihilate ''everything'' living, including ultimately themselves. As both demons and devils have no interest in killing literally everyone, they don't get on with daemons. At all. They will team up with each other and ''FUCKING CELESTIALS'' to stop Daemons from eating the river of souls they all use.

The last involves the chaotic Proteans, who are trying to dissolve the Abyss into the Maelstrom (the only plane rivaling it in size) believing its creation or opening into the rest of the multiverse to be caused by their mistake. Proteans warred with first the Qlippoth (the first great planar war, before any other planes besides the Maelstrom and Abyss spun out of the Maelstrom and into existence) and now the Demons. The Proteans spend about as much effort facing the [[Inevitable]]s of the aggressively expansionist lawful plane of Axis, so they're not able to focus fully on either fight.

The one area Demon vs. Devil ''does'' come up in Golarion is in the devil controlled nation of Cheliax. There it is categorized merely as devils keeping hold on their power: Demons are merely a third party trying to take power from the Devils and must die because of that. A handful of mentions of state sponsored demon hunters exist, but virtually no information is given on them. Cheliax actually wants the World Wound, a planar rift spewing out Demons, to stay open since it means all the crusaders, paladins and good aligned clerics that would otherwise oppose the Devil run country go there to die instead.
