But you couldn't be or do Elric under those limits. Not the cosmology change. That's doable without even deleting the Wheel(see Eberron). You could play a non-Elric/Eternal Champion in one of those universes, but if you want to be like the books, it will take more.An Elric setting would delete the Wheel, and only have LLE Acheron and CCE Pandemonium, plus maybe a Neutral (Good) Astral Plane. These alignments would interact to generate and influence the Material Plane. There might be an endless number of parallel Material Planes.
In this setting, D&D rules can work normally. Or it can cap at level 8 and ban fullcasters to assist the sword and sorcery feel. If so, interaction with alignment forces and a Relic like the sword Stormbringer would be DM fiat.
The closest that I can remember would be Tanelorn, the eternal city of peace/rest. That's not really an afterlife, though.(I forget if the novels describe how an afterlife works.)
