Desert Worlds

Dune seas under a permanent wind-borne dust haze.

A desert world is a hot, bone-dry rock that kept its atmosphere: with no water cycle to wash the air clean, wind lofts a permanent veil of dust that softens the sky into haze - endless dune seas, wind-carved rock, scorching days and freezing nights. Build one with a dry silicate recipe near the inner edge of the habitable zone, keeping hydrogen low so no oceans ever form; a dash of sulfur turns the sands pale gold.

A binary star system's orrery: two suns close together, a red dashed dead-zone boundary, and a debris trail left by a destroyed world

New: Binary Star Systems 🌀

A system can now orbit two suns. Add a companion star when you build one — close, medium, or wide — and the physics decides what survives: a shared center of mass carves out a dead zone where gravity from both stars tears a world apart, leaving it as debris, and every surviving planet's orbit goes elliptical, moving fastest at closest approach and slowest out at aphelion. Push the separation to wide and the dead zone opens tens of AU across, wide enough to gut a system that would have been stable around one star alone. Stand on a world that made it through and you'll watch two suns cross the sky together.
