Hypercane

Hypercanes first appear in Dark Age as colossal, engineered storms capable of 800 km/h winds and total sky coverage, weaponized by the Society to scour the surface of Mercury and trap the Republic's forces. Across the series these storms evolve from mere atmospheric weapons into symbols of planetary-scale warfare, their existence revealing the lengths to which both sides will go to deny territory to their enemies. Their deployment marks a grim escalation in the conflict, transforming entire worlds into uninhabitable battlegrounds and underscoring the saga's shift toward existential stakes.
