“A ritual vessel used to channel Hollow Earth energy, shaped as a wide stone bowl set within a bronze ring frame. Carved runes line the rim, filled with faint green-amber luminescence. The stone surface is rough and stratified, with mineral inclusions and age cracks. The form is bold and readable, avoiding fine detail. Centered against a pure white background, softly illuminated with neutral studio light, minimal shadow. Ultra-realistic PBR materials with stone roughness, bronze oxidation, and subtle glow.”
