Umbra Twisters

Umbra Twisters first appear in Dark Age as towering, 90-meter chalk dust devils that scour the surface of Mercury, coating skin and lungs with a fine, toxic film. Their emergence marks a new environmental hazard in the war-torn planet’s already brutal landscape, forcing both Republic and Society forces to adapt tactics and equipment to survive the abrasive storms. As the series progresses, these twisters evolve from mere atmospheric phenomena into strategic weapons and symbols of Mercury’s unforgiving terrain, shaping the course of battles and the fates of key characters.
