afroakuma's Planar And Other Oddities Questions Thread VII

[rigsmal]

Does Gothic Earth a la Masque of the Red Death exist in the canon cosmology? If not, how should I force-fit it in? Separate material plane?

Edit: Also, you mentioned Eberron potentially being contained in some crystal sphere. What are the pros and cons of having Eberron in a crystal sphere vs. a separate material plane? Does anything break if I treat it as a separate material plane and force-fit all the outer/inner/transitive planes into the usual cosmology?
