A formidable snow dragon soars through a stormy, winter sky, its massive wings creating gusts of icy wind and swirling snowflakes. The dragon's scales glisten with shades of frosty blue and silver, reflecting the cold light of a full moon partially obscured by dark, snow-laden clouds. Its piercing, icy blue eyes glow with a menacing intensity. The background reveals a rugged, snow-covered mountain range, with jagged peaks and frozen cliffs. Lightning occasionally illuminates the scene, highlighting the dragon's powerful, sinewy form as it exudes an aura of ancient, magical danger.
