Once upon a time there was chaotic madness, the churches fought like secular noblemen. We have learned since then.
Gregarius whiteblood, spokesperson of the Holy Alliance

Before there was a strong king to keep the nobles in line, before the universities started upon in the cities, before the Xoorvintal dragons stopped killing us for sports, there was the gathering of faiths. The good Religions, and most Neutral as well, unified under one banner, as to give their worshippers more power. Today this manifests in every city, as most worshippers are welcomed in the temple. If the city can only afford one temple it will be dedicated to their patron deity, but at least one altar is cept clean to cater to the desire of different clergymen. The market of potions is kept under strict control of the church. Every member church is an affilition of it's own, but share these basic traits. In return, the benefits can be reaped in any sufficiently large city.
