The Sunscoured Flats

A vast arid desert under a fierce white sun and slightly heavier-than-Earth gravity. Liquid water survives only in deep aquifers and brief dawn dew; days scorch, nights freeze, and relentless wind drives the dunes across cracked salt pans.

More robust and reclusive than its ancestors, it spends most of its time deep underground, only briefly surfacing to hunt.

Why it evolved

A virulent disease or parasite load selects for individuals with enhanced immune responses and physical defenses, leading to a thickened, more resistant cuticle. To minimize exposure to airborne pathogens and the intense daytime heat of the Sunscoured Flats, the Dune-Scourer becomes more subterranean, investing in stronger burrowing appendages. This increased reliance on burrowing comes at the cost of reduced surface foraging efficiency and a slightly smaller overall size, but improves survival against disease and the harsh diurnal temperature swings.
