Ancient Steel Guardian Description (≤800 chars): This 3D model depicts an ancient robot from a long-forgotten civilization, inspired by the style of classic steel giants. It stands tall and imposing, built from weathered metal plates with deep scratches, rusted seams, and faded markings that hint at lost technology. Its limbs are thick and mechanical, connected by large cylindrical joints and exposed inner gears that turn slowly with each movement. The chest features a dim core light, pulsing with weak bluish energy like a relic struggling to awaken. The head is simple and helmet-shaped, with two soft glowing eyes that convey wisdom and sadness. Heavy footsteps and faint metallic echoes give the robot a timeless, ancient presence.
