Deity Worship

Elemental Gods - Created by the raw magic of Lume during the formation of the planets, sun, and moons. Each embodies an aspect of nature and is the personification of the will of Lume. Most of these gods don't have an organized church but devout worshippers of each can be found. Those that do have an established church are not as active in converting as the outer gods because their power is derived from Lume itself and not the spiritual energy of their worshippers.
Outer Gods - After sentient life formed in Lume, the outer gods took notice of the world and descended from other planes to convert worshippers to gain their spiritual power. They brought the knowledge of good and evil to the world and eventually began a war between the forces of good and evil. The cataclsmic powers unleashed during this war changed the faces of the planets, destroyed life (including a few gods), and eventually woke the will of Lume. When Lume awoke it banished all gods from the plane so that they could only interact with worshippers though signs, portents, and granting powers.

Druidism

Follow the will of Lume
All things in Lume have a spirit that is part of Lume
Reincarnation - All mortal beings in the realm of Lume exist in the wheel of death and rebirth except for dragons (see Dragon Priests) and devout worshipers of the outer gods (who are taken to the gods plane).

Spiritualism

Dragon Priests - When dragons pass from the mortal world their spirits do not enter the outer planes or step back onto the wheel of life. Instead they remain in Lume as powerful spirits. Many dragons and some other beings make pacts with these spirits in exchange for power. Dragon Priests are Clerics that can choose any two spheres (as appropriate for the individual dragon or dragons) but only have access to spells up to 6th level.
Ancestor Worship - Powerful ancestors sometimes watch over their family for a time before stepping back onto the wheel of life. Some families have learned to channel the power of their ancestors. Clerics of ancestor spirits can choose any two spheres (as appropriate for the family) but only have access to spells up to 3rd level.
Spirit Cults - In the spirit world surrounding Lume, there are numerous spirits that can offer guidance and some power. Clerics of the spirits can choose any two spheres, but only have access to spells up to 1st level.
