Slagworld

Lava World
Centuries of industrial waste have left this world a grey-orange marble of cooling slag. No one lives here, but automated barges dump refinery tailings on the surface around the clock.
Touched down on Slagworld this morning—a planet that makes a mockery of the word "hospitable." The surface is a roiling hellscape of active volcanic zones and obsidian plains that still radiate enough heat to warp the hull sensors, yet there's something hypnotic about watching lava lakes pulse like a planetary heartbeat under that blood-red sun. I've catalogued three distinct magma chamber systems, each volatile enough to warrant a wide berth, but the geological activity here is so violent and pristine that I can't help but wonder what secrets the deeper layers might hold—assuming anyone ever finds the nerve to dig. Remind me why we don't just mark this one as "too toasty" and move on; my coffee tastes like recycled air when I'm this close to an open mantle.
