Editing World Tree (section)

==Changes from the Great Wheel==
Unlike the Great Wheel cosmology, there is no attempt to balance the alignment of the World Tree model, nor are they defined by a set of moral philosophies; the planes are not necessarily situated next to their closely aligning neighbors, nor are they situated across from their diametric opposites if they have one. "Planes" exist more as clusters of deific realms rather than as self-sustaining dimensions and are organised more according to the deities which inhabit them; what links they have made with each other; and those links can forged and broken as the plot advances.

This has the advantage of making the cosmology quite fluid, where planes can move and shift as deities rise and fall, rather than being locked into an aligning location. Indeed, different depictions of the World Tree model have different numbers of planes on each side of the tree, and in different positions. In the World Tree Cosmology, gods tend to inhabit the realms of their sponsors or allies regardless of their own alignment and can create areas that would otherwise overlap and blend into each other in a Great Wheel and potentially create friction at the borders which cause portions to drop into one another like they do in other settings. Instead the planes are kept distinctly separate in the World Tree and are only connected through the various astral links.
