What is Eberron's Religion like?
Interestingly different. There are no deities who make their presence felt explicitly on Eberron, and depending upon their viewpoint on the origins of divine magic, a character in Eberron could conceivably be an atheist.
The main religion is the Sovereign Host, a pantheon of several deities who are generally worshipped as a group, though temples and clerics to individual Sovereigns exist.
The opposite side of that coin are the Dark Six, deities who are considered, by most civilised humanoids, to be evil and deadly, but who are commonly worshipped amongst monstrous races, who may see them rather differently.
The closest thing Eberron has to a deity one can point to and say "that's real" is the Silver Flame, which is worshipped most devoutly in the nation of Thrane. A lawful-good religion in structure, the Flame is dedicated to protecting civilised lands from the forces of evil (or at least, whatever they currently define as evil). The Flame has a physical presence in the capital city of Thrane, and even issues commands via the head of the church, the Keeper of the Flame, but it is not truly a deity - rather it is the embodiment of many celestial creatures who gave up their physical forms during an ancient battle.
The structure of religious organisations in Eberron differs from that in other settings somewhat. For one thing, the requirement that a cleric be within one step of their deity's alignment does not exist here - a corrupt or misguided cleric of the Silver Flame could easily be Chaotic Evil. Also, since NPCs generally have NPC classes (even the minority with PC classes will generally have NPC classes as well), there aren't as many clerics in these religions as you'd expect. A temple in a town or village might be staffed purely by Experts and Adepts, and even one in a major city might have only a handful of clerics.
Finally, religions in Eberron are not generally open for business. Clerics do not openly offer healing or resurrection as services for gold, instead reserving these for particularly devout or important members of their faith (and in the case if resurrection-type spells, only a handful of NPC clerics are sufficiently powerful to be able to perform such miracles). If you're clever, lucky and persistent, you might find a corrupt cleric who's prepared to offer such services as a sraight transaction - if not, you might be asked to perform some quest or task on behalf of the church in return for their assistance.
