Something always survives, something always thrives.

The biosphere of a planet goes kilometers down and bubbles back up in hot geysirs and moving rock.

So the evaporated oceans rain down on hot obsidian, collecting at some places, seeping below at others hollowing out halls and caves below, natural hot houses.

Within it regrows the thinned out remains of a once mighty biosphere. Plantseeds, swept away and then burrowed in muck under lava, spores that survived in the atmosphere, seeds even a lonely bird might have carried away from the blast wave.

Given the radioactivity, evolution is fast, harsh and distinct. There is a outside biome, rewarding flying predators, and a inside biome, rewarding speed, heat-resistance and the ability to slither through razors harp cracks.
