Umbra Twisters first manifest in Dark Age as towering, 90-meter chalk dust devils that scour the surface of Mercury, coating skin and lungs with a fine, suffocating film. Their appearance signals the planet’s environmental collapse under siege warfare, turning the battlefield into a choking, white wasteland. Across the series they evolve from mere atmospheric hazards into strategic weapons that both sides learn to weaponize or endure, reshaping tactics and survival on Mercury.
