"dungeons and dante's inferno" pops to mindPersonally I'm partial to an "Afterlife" plane. Neither heaven nor hell, it simple exists. Some -parts- of it might be hellish. some parts heavenly. But most people aren't evil enough to be consigned to hell, nor good enough to pass into heaven, so they just meander about in the Afterlife.
If course... if you're skilled enough, you could escape hell into the regular afterlife. Or even sneak into heaven.
Much more fun, to me, than separating out the planes.
