As far as I can tell, there is no factionwide bonus for religion in Age of Charlemagne.Christianity is located all throughout Europe during this time period, mostly in France and some of Germany. It reaches into Britain, Iberia and some of the lands to the east as well.As far as I can tell, there is no conversion mechanic in Age of Charlemagne. However, you can convert the people who practice this religion in the locations where it is most prevalent, listed above. This is reasonable to an extent, because at the time there were not nearly as many religious conversions as there were in the Grand Campaign’s time period.All of the factions with Christianity are listed here. If any are missing, it's because the wiki does not cover this DLC very well, and most of my resources come from in-game. They are (mostly) all playable:The building chain is different in Age of Charlemagne. There are minor religious buildings for Christianity, with standard public order bonuses (as well as adjacent region bonuses, too), religious influence, priest recruitment, and religious osmosis bonuses. Best of all, these buildings are purely beneficial—they cost no maintenance at all.There are no specific major temples in Age of Charlemagne, it works based on the major settlement itself. The major settlement has to build a “cathedral town” in order to offer a religious bonus. This temple offers bonus imperium, public order, religious influence (adjacent too), religious osmosis, and priest recruitment. These bonuses are on a larger scale, and require the construction of a religion-specific settlement chain. These bonuses are large than the minor settlement options, of course. It does come at a cost of -80 food, at tier four.There are no specific edicts for Christianity in Age of Charlemagne. This is likely because you cannot convert, either. However, the edicts are tied to each faction, and I will list the Christian factions' edicts below.For the time period, yes, Latin Christianity was reforming and taking over Paganism in Germany. The numerous factions are fighting for control, both in conquest and faith. Greek Christianity to the east was having trouble expanding, but Latin Christianity religion was exception to that. This is up to you, but the crusades are coming—in about 400 years. But they won’t wait for you. Personally, I would choose this or Islam, because of my historical interests.
