Generated from: Game inventory icon of a single round seal disc, isolated on a plain flat background, viewed straight on at a slight three-quarter tilt, dramatic soft studio lighting from upper left. The disc is a heavy slab of grey weathered stone bound in a rim of dark blackened iron. Carved deep into its face is a schematic floor plan: rectangular chambers of different sizes connected by straight corridors, laid out like an engraved dungeon map, with a small Keeper's rune in raised relief at the exact centre. The engraved map grooves glow with faint cyan-blue rune light; the raised stone stays matte and unlit. Chipped edges, fine cracks, dust in the grooves, subtle bronze inlay dots marking the chambers. Norse dark-fantasy dungeon art, painterly semi-realistic game asset, rich bronze-and-slate palette with cyan rune accents, high detail, crisp silhouette, no text, no letters, no border, no frame, single object only.
