A magical knight’s shield shaped like a traditional heater shield

A magical knight’s shield shaped like a traditional heater shield, crafted of burnished gold alloy. The surface is polished to a near-mirror shine, reflecting the ambient light with a soft blue aura. At the center, a proud silver lion emblem is embossed in high relief, surrounded by concentric arcane runes glowing faintly with magical energy. The edges are reinforced with bronze filigree. Subtle magic motes float around the shield. Style is fantasy semi-realism, reminiscent of D&D 5e equipment design, highly detailed textures, luminous glow, engraved symbols. The shield rests in front of a stone wall in a hero’s armory, warm golden light contrasting with cool magical blues. Rendered with cinematic lighting, clean outlines, heroic tone.
