She wields a massive, intricately designed longsword with a glowing, crystalline blade, exuding an aura of ancient magic. Her dark, flowing robes are adorned with ornate metallic armor pieces, glinting with golden and silver accents. Her skeletal hand, wrapped in mystical engravings, grips the sword hilt, emanating an eerie glow. The background features a blizzard-like setting with jagged, frozen mountains and shards of magic energy swirling in the air. The atmosphere is dramatic, dark, and filled with energy, capturing a moment of immense power and mystery. Ultra-realistic, high detail, cinematic lighting, epic fantasy style.
