The feather gleams iridescent under your fingers, soft as down yet rigid at the quill's edge, pulsing with faint, captured winds. Crushed in your grasp, it bursts into a thunderous flap, birthing a massive eagle whose talons scrape stone and wings whip gusts that sting your skin like icy needles. It soars skyward, feathers slicing air with a resonant whoosh, eyes piercing the horizon in unyielding focus.
