A silver-haired battle mage with glowing amber eyes, a curvy athletic silhouette and ornate white-and-gold combat robes stands on the surface of a frozen lake while an endless undead cavalry army charges beneath a solar eclipse, she raises one hand and hundreds of golden runic circles unfold across the sky, firing crystalline spears that impale the first ranks while she glides backward across the ice, bends around incoming arrows and creates floating symbols beneath her feet to accelerate above the battlefield; a gigantic skeletal dragon suddenly erupts from beneath the lake, shattering kilometers of ice and throwing her into the air, the creature opens its jaws and unleashes a torrent of spectral fire, forcing her to spin through the blast, redirect fragments of ice into shields and launch herself toward the dragon’s skull while thousands of undead soldiers climb its bones; she lands between the horns, tears open a massive circular sigil above the clouds and pulls down a radiant spear larger than a cathedral as the dragon rises vertically toward the eclipse; high-end epic fantasy anime, breathtaking spell sakuga, graceful but ferocious movement, fast aerial camera orbit, extreme close-ups of glowing pupils and trembling fingers, huge scale contrasts, dynamic camera rolls, highly detailed cel-shaded character animation blended with massive creature CGI, icy cyan ambient light contrasted with molten gold magic, snow, luminous mist, shattered crystals and white lightning, transcendent supernatural atmosphere, ending with the mage hurling the colossal spear through the dragon and directly into the eclipse, creating a sun-bright explosion that vaporizes the undead army and restores golden daylight across the frozen world.
