In the spirit world you can find spirit beings created from a variety of sources. There are animal spirits who represent the essence of what it means to be a fox, eagle or other animal. There are emotion spirits, the essence of love, hate, fear, etc. There are elemental spirits of the material elements (air, earth, fire, water, metal and wood) as well as energy elements (light, dark, stasis, change, essence, resonance, tide and vortex).
Each of these is a fragment of its great spirit, an ethereal being of divine power who resides in the Maelstrom and has its own immortal realm. The realm of the Great Spirit of Hate is a very different place to the realm of the Great Spirit of Change or the Great Wolf Spirit. Much as gods have mortals to worship them, great spirits have their lesser spirits to rule over.
