Uninhabited Extreme-Heat Regions of Earth

Barren expanses across Earth's surface bake under relentless solar assault, their sands and rocks radiating intense heat that scorches unprotected skin and warps the air with shimmering mirages. Humanity ignores these desolate zones, drawn instead to temperate lands, leaving them empty of settlements or cultivation. The Doctor pitches them to the Silurians as perfect refuges: their reptilian bodies thrive in the sweltering conditions, enabling revival of ancient colonies without clashing over populated territories. Winds whip dust across cracked earth, carrying a dry, mineral tang, while isolation amplifies the promise of undisturbed survival amid towering dunes and jagged outcrops.
