Hey all. I've having a bit of an issue customizing the cosmology for my campaigns, and was hoping some of you cutters could offer any suggestions, or someplace to look for inspiration.
I'm essentially using the Great Wheel cosmology, to the best of my understanding of it. I'm including the Spirit World variant plane from Manual of the Planes (3E), and expanding the relevance of the Region of Dreams. After giving some thought to the location of these planes in relation to the rest of the multiverse, I decided to make the Spirit World coexistent with the Material Plane, with links to the Astral Plane and Border Ethereal. Such a position also seemed a good place to put the Faerie Realm (which may have been inspired by the seemingly similar placement of 4E's Feywild), also coexistent with the Material Plane, and connecting to the Positive Energy Plane, the Beastlands, Arborea, and Pandemonium.
I would like to keep with the Rule of Threes, and have a third such plane overlapping the Material, but I'm coming up short on ideas. I've looked through the Manual of the Planes' variant chapter, and took a look at a couple of published campaign settings' (Forgotten Realms and Pathfinder's Golarion) cosmologies, but nothing is inspiring me yet.
Similarly, I've given thought to the placement of the Region of Dreams. I had originally thought to use it for my third plane overlapping the Material, but those planars that sleep still dream, right? So it seems to me that the Region of Dreams would be further-reaching than just the Material Plane and a few points on some other planes. So I'm currently thinking to make it coexistent with the entire multiverse.
But it doesn't seem quite right to me to have only one plane with such scope, so I'm trying to round it out to three again. I'm considering the Plane of Shadow as a second. I don't know if that one quite fits though. I'm still not entirely certain if the Plane of Shadow is supposed to just be close to the Material Plane, or if it reaches the rest of the multiverse.
The Temporal Energy Plane was another I'd considered, but given the inconsistency of the passage of time on various planes, I don't think I would want to put it on the same scope as I'm placing the Region of Dreams. The name makes me want to set it at the center of the Inner Planes, between the Positive and Negative Energy Planes...
Any thoughts or suggestions?
