Kraunsheg A world of gravity gone awry, where the pull of weight is so strong that even an average human produces enough to easily walk upon, and every native inhabitant flies though the open space because to touch the Black Wall at the edge means a rather messy death from collapse and implosion.
Elehaven Tired of being at the beck and call of spellcasters in the rest of the cosmos, elementals crafted a planar retreat which would allow them to withdraw and retire from the rest of the multiverse when they wish. All elements can be found there, if you can find it at all- for the primary trait of the plane is that Conjuration, Divination, and even Universal spells just don't work... (wouldn't want a sneaky Wish to get around the restrictions now would they?)
On a side note, I long ago added a function to my private utility programs to generate a random demiplane using the tables in MoP (with the additions I made to those rules such as the existence of Vacuum-Dominant, Electricity-Dominant, etc. planes). Its results can often be quite strange, but very inspirational if you take the time to think about what they mean.
