Evolved from cliff-dwelling swallows who transformed nesting-site navigation into lethal combat gliding. These warriors emerged when traditional aerial fighters faltered in The Arena's constricted zones, proving that survival often depends on mastering overlooked spaces rather than open-air dominance.

Compact physiology enables rapid directional shifts in tight spaces. Friction-resistant primary feathers allow wall-grazing maneuvers without injury. Enhanced spatial awareness permits blind navigation through echo-location during high-speed glides. Reinforced wing joints withstand constant collisions with stone surfaces.

Specializes in disrupting enemy formations from unexpected angles and mapping arena vulnerabilities during combat. Serves as Birbs' primary reconnaissance and shock troops in multi-level battlegrounds.
