Some of the players in my group, who know me to be a fan of planar cosmologies like 2e/3.X/5e's Great Wheel and 4e's World Axis, have proposed that I run Planescape's Great Wheel with a twist.

There is no Prime Material Plane, and there never was. There are and were no mortals.

The elementals of the Inner Planes and the natives of the Transitive Planes become petitioners in the Outer Planes upon death, who then become outsiders. When an outsider dies, nobody knows what really happens; some say the outsider merges with their plane, others claim that the outsider reincarnates, more still posit that the outsider ascends to a higher reality, and a pessimistic few point to oblivion.

Could this kind of setting work without regular mortals and a regular Prime Material Plane? I imagine that the closest thing you could get to "regular people" and "regular worlds" are air elementals living in floating earth-motes in the Elemental Plane of Air, or perhaps vacuum quasielementals living on immense rocks in the Quasielemental Plane of Vacuum.

I have run settings wherein nobody needs to eat or drink before, so partial post-scarcity is something I know how to handle.
