World Pantheon (20% of people of Aernth are followers of this religion) It is a multi-theistic religion, different from anything else (but it has some aspects that are similar to several real world religions, such as the Greek or Norse religions).
Church of the All Father (15% of the people of Aernth are followers of this religion) It is a mono-theistic religion, in which there is a single "God" that is refereed to as "The All Father" or sometimes as "Jailsahaim" (this religions sort of resembles the Catholic church of medieval times in Europe, but the resemblance is quite limited).
Druidism (20% of the people of Aernth are followers of this religion) This religion is what the name implies (I utilize what I know about the religion as it existed in Ireland prior to the arrival of Christianity, but since the information about it is quite limited, I have used quite a bit of "Creative License" to change or alter it to fit the needs of the game setting.
Jailsahaim (10% of the people of Aernth are followers of this religion) This religion most closely resembles the Jewish religion (it is based off the same deity as the Church of the All Father, except they believe that the "Messiah" has not yet appeared, and several other doctrinal differences also exist between them).
Totemism/Shamanism (10% of the people of Aernth are followers of this system of beleifs) The concept of Totemism or Shamanism dates back to the earliest of times and oldest of cultures. It is in essence the interaction of beings in the worldly realms of existence with animal and other nature spirits from the Menagerie, Astra, or Spirit World. While this system of beleifs is most common among barbaric cultures, where technology is at a minimum (think in terms of the Australian Aboriginies, the American Indians, or some early African Cultures), it can still be found present in some rare advanced cutlures. While this is system of beleifs closely resembles Druidry and they interact extensively, it is different. Where Druidry is very well organized and structured, Shamanism is not. It is usually specific to the local culture and area.
There are also several smaller organized religions present, but they each have less than 5% of the people of Aernth as followers (most are under 1%), and thus are not discussed in any detail here, but if you are running a character that wishes to follow the doctrine of some other religion that is not listed above, let me know and we can probably work something out for you.
