Ploeperpengel is right WFRP is way out of date and is no longer canon... (atm anyway) but i dont see anyway to get around using it. It covers alot of stuff that is needed Nippon, Cathay etc that would be impossible to cover without it. I dont mind using it EXCEPT when goes against current canon.
Rule of WFRP use
1.
It must not go against current canon
e.g Khaine as the lord of murder for elves not humans as well....
Faiths:
Old Faiths:
-Most of old World (the old faith) to my knowelge it was only worshipped in what
is now Brittonia, Albion and the Empire. Esatlia, Tilea, Brittonia, Araby and parts of Khemri were ruled from Tilea (roman empire of warhammer) they persecuted the old faith, and it died out everywhere except Albion (where it is stilled worshipped). I would love to see it included but is it really important?
Asuryanism: (for PC reasons it should be changed to Cult of Asuryan, cant discreminate between "evil" and "good" elves. ALL ELVES ARE EVIL!!

)
-yeah i guess it represents the High elven view of their gods
Cult of Khaine:
-represents the Dark elves and their really warped version of faith, they forsook all the other elven gods because they believed they were betrayed by them.
Followers of Isha:
-represents the wood evlen view of the way the world works
Dwarven Pantheon:
-go figure its right

but... when did the Chaos dwarves spring into being?
The Old Ones:
-to my knowelgde it isnt really a relgion the slann are really really old and they know that the old ones are going to be coming back, its just a matter of time really... Slann are the caretakers of the world that the Old ones created specially for this role
-Amazons well im not a 100% sure but i think they do venerate the old ones maybe as gods? not all powerful creator beings that are mortal.
-Note: the Elves know that the old ones created the world, although they were not old enough or advanced enough to understand why?
Ormazd:
-that is from WFRP i gather. It gets my green light to be used for lack of other infomation.
Ind Pantheon: (Should be put here)
-Note Ind is the oldest human Civ and their gods are hinted to be memories of the old ones (cant say that emphatically)
-They have been worshipping the same gods for a long long time... they have a tiered system of gods though. The original gods of thier pantheon which are strikingly similar to the old ones.
-They also have a 2nd tier of gods that have devolped over time (based on heros etc)
-They are now up to thier 3rd tier of gods which have devolped over time yet again (based on legends)
-These new and newer gods are children or have an affinity with the previous line...
-They still worship the oldest gods but they are not as popular as the current gods (for more infomation look at the tiers in the gods in real world India)
-Infomation drawn from WFRP, Warhammer and some of my own conclusions based on the limited infomation.
Cult of Celestial Dragon:
-Cathay im led to believe is also damm old nearly as old as Ind, but its a choice really it could fit into Young, Old, or God of Order
Jintoism
-Same with Nippon just use it a balancing factor to have an even spread of religions popping
Animism:
-would add this for the very early old world (just make it default for civs without a religion, Paganism is so baised and unfair)
Young Gods:
Old World Pantheon: Morr, Ulric, Rhia, Manann, Verena, Haendryk, Myrmidia, Luccan, Luccina
Norse Pantheon: Thor, Odin etc
Kislev: House Spirits
Chaos: they are young gods or at least some of them
Drop the rest of them down to a new Civic Patron Gods or into Gods of Law
Dark Children
Hieratic Order
-been reading up about Tombkings they are not Nagash supporters... but im not sure if they still worship their old gods (im lead to believe they are a bit jaded in that respect) but they are still devoted to tradition.
Aristocracy of the Night, Chosen, Blood Kiss? leaning towards Chosen or Blood Kissed/Kiss
-Lhamians sorta just stole what Nagash knew... they dont really worship him, and they sorta buggered up his incarnation anyway and improved on it. But they did worship themselves.
-Sylvanians though they are sorta 4000 years distant but oh well....
The Horned Rat
-Skaven (why not put them into Chaos? or throw Beastmen in here as well they are both Dark Children products of Warpstone and Chaos...)
Chaos Dwarves (throw em in Chaos for simplicity)... No idea what they hell....
Chaos Cults
Tribes of Chaos
-represents the tribes of men that follow Chaos, Dolgans, Kurgans, Wu etc... most of them never worship the main Chaos gods they worship a minor servant or aspect of the god... throw the norse in here as well (i think the different gods special stuff could be a bit later somewhere or just represented with buildings etc)
Children of the Dark gods
-Beastmen are chaos incarnate they are the product of Chaos... maybe put em into Dark Children?
Fallen Brethren
-Chaos Dwarves their wills be a word that the dwarves use to describe them and it wont be pleasant
The Horned Rat
-throw them into children maybe...
Cult of Pleasure (im not sure about if this is needed...)
-Darkelves are evil and sadistic and hedonistic at the same time this lot are just worse...
Ind
-Chaos? they got invaded during the great war against chaos...
Gods of Law
Cult of Celestial Dragon (covered allready)
Jintoism (covered allready)
Ormazd (AKA) Al-Alnon
they do change how their pantheon is made up so yeah
Sigmar-du^m
-i vote we obliterate this farce...

someone must be sitting in GW and regretting this ever making it into the light
Asuryanism- let it be and just keep it in Old Faiths
Patron Gods (they are not old gods, and they are later than the new gods...)
Sigmar
-not really a god but treated as one more of a patron saint that anything, more powerful than that though
The Lady
-patron saint but more powerful than that though
Ursin
-same thing as above...
Barbaric Gods:
-Orcs (Gork and Mork)
-Gobbos (Gork and Mork)
-Hobgoblin Hegemony (Worship of the Great Khans?)
-Ogre Lords (The Great Maw)
Yeah to all scrap horned rat from this...
