Primo piano di spada antica runica

Cinematic close-up of a legendary ancient sword crafted from dark forged steel. Glowing arcane runes are etched deeply into the blade, radiating molten [crimson and gold] light from the carved grooves. Ambient ember sparks drift through the air alongside subtle wisps of smoke and faint heat distortion. Dramatic directional side lighting, high contrast, deep shadows, set against an atmospheric dark background.
