A realm of sundered reality - dead now, a maelstrom of shattered cultural artifacts and bones. Like a zero-gravity equivalent to the outcome of a massive Tsunami. Houses, boulders, globs of water and earth, the artifacts of a lost world, all floating, all surrounded by air.
Sunlight spears in from shards in the sky, which itself is a patchwork of thousands of skies. Some parts are clear blue, others hold pieces of the sun, moon(s) or other bodies. Storms and gentile showers, snow and hail.
Time itself advances in fits and spurts, occasionally even reversing. The direction is, however, towards greater and great entropy, and eventually all that will remain in the realm is scattered dust.
Treasures can be found in this floating graveyard, though the jumble of objects is very dangerous, and while the world is largely dead, there may still be _things_ lingering about, as chaotic and shattered as their world...
