Dliny the Elder, A History of Religion wrote:
Legends tell how The Almighty Goddess, The World-Mother, in Her infinite love of sentience, sacrificed her own heart to become the world - a home for all, and that all live sprang forth from there. The veracity of this creation-myth is impossible to ascertain. Clerics are unable to communicate with Her, for She answers no prayers and grants them no powers. Some druids worship Her and claim that their powers come from Her, but this is also impossible to confirm. Some druids ignore such legends, worshiping only Nature itself, and perhaps even dismiss such legend as myth, yet they still have druidic power. The faithful argue in return that She is Nature; Her heart is the world, Her soul the universe, the gods her lifeblood, and we are all Her glorious creations. By worshiping Nature, or other gods, they link themselves to Her, and Her blessings flow through them.
It is, at least, a good story, believed by most, yet ignored even by many of those who believe. Whether one believes it or not seems to have little effect on one's life.
The gods of the world often seem almost limitless to a casual observer. While they do not directly interfere in the affairs of mortals, and dwell far beyond what the spells of the greatest wizards can ever hope to penetrate, they do seem to answer those who tap into the divine. Most of the great cultures have their own pantheons, and yet none can argue that their own are true while the others do not exist. A Dwarven orthodox cleric in exile weilds no less powerful divine magic than a prestigious High Priest of the Celestial Bureaucracy of the Glorious Empire of the Sun. Many believe that the pantheons simply represent the stylings and mortal legends given to celestial concepts that we can understand - many pantheons having analogues of each other's deities, and perhaps, ultimately, all the Gods are linked together and part of Her.
The pantheons of the world are as follows:
The Asgardians (Deities & Demigods)Among the most widely worshipped in the world, the Gods of Asgard may have closed access to the rainbow bridge millennia earlier, but Odin, Frigga, Thor, Sif Tyr, Heimdall, Freya, Balder, Hel and many others answer prayers of the Nordic people and any other who convert (including many isolated elves dwelling in the mystical Alfheim mountains separating the two nations.) The dwarven people, too, once worshipped these gods, before the revolution that installed the Dwarves' Republic of Nidavellir.
The Celestial Bureaucracy (must be created) - religion of the Glorious Empire of the Sun
The Elvedic Panthon (must be created) - Elven pantheon loosely based on Hindu gods and goddesses
The Olympians (Deities and Demigods) - Primarily believed in by the Empire of the Moon, who worship Poseidon as their father, many people of all races along the coastal areas also follow the gods of Olympus.
I still need a gnomish pantheon, which I'm tempted to rip from forgotten realms, wholesale (Garl Glittergold and company.) Nevermind how tempting it is to give our tiny megacapitalists the religion of the Ferengi from Star Trek.
