(4) Based on the lore so far, here is a preliminary list of phenomena that any good planar theory should address. I hope this can serve as a model for a variety of planar theories in the future. Finally, I can also state the specific function of planar theory.

Planar theory seeks out the best metaphors for explaining the 'planar phenomena,' which can be grouped under the following categories:
1) the planes
- their creation and destruction, their elemental compositions and levels of development, dimensional barriers and weak places, mystical resonances, etc.
2) the abyss
- pockets, its uses, etc.
3) the void
- as empty 'space,' as the absence of the abyss, as a barrier between worlds, as a spatial 'pocket,' as related to dimensional straddling, as a means of travel for pests, etc.
4) shadow realms and related phenomena
- such as spirit realms, dream worlds, etc. and their uses, etc.
5) pocket dimensions
- their creation and destruction, 'flattening magics,' etc.
6) portals
- teleportation, rifts, portal dynamics, portal systems and nodes, stability and instability, openness and closedness, the role of talismans, the role of energy in using or collapsing portals, etc.
7) 'planar distance' and other relations among the planes
- such as between Gielinor and the spirit beast's realm or the Land of Snow or Agrith-Naar's world or Zanaris, the Zanarisian eclipse, aetheric threads, the relations of planes to memory, anima, and spirits, etc.
