傳說中的龍之鍛造長劍，綻放深紅光芒

A highly detailed fantasy illustration of a legendary longsword in classic Dungeons & Dragons style. The blade is steel with a faint crimson glow along the edges, hinting at latent fire magic. The hilt and crossguard are crafted from polished red dragon fangs and bone, curved and menacing yet expertly forged. Set into the center of the hilt (or pommel) is a symbolic red dragon element—either a carved dragon sigil, a dragon-eye ruby gem, or a small embossed dragon skull—clearly showing the weapon was forged from a slain red dragon. Subtle flames coil around the blade, as if the sword can ignite at will, embers drifting through the air. The sword rests against a dark stone background, illuminated by warm firelight, giving a sense of ancient power and mythic craftsmanship. Epic fantasy weapon art, high detail, dramatic lighting, no characters, no gore, magical aura, heroic tone, D&D classic aesthetic.
