ancient ruin block 3d model

A stylized low-poly ancient movable ruin block for a fantasy puzzle RPG game. The object is a tall rectangular stone wall fragment, about human height, occupying one square or hex grid cell. It looks like a broken piece of an ancient wall, not a natural rock and not a fixed building. Simple large stone slabs, hard edges, clean low-poly shape, readable silhouette, no tiny details. A single glowing cyan energy band wraps around all four sides at the middle height. The front face has one simple large diamond-shaped carved panel. The top has a simple square cap with a small inactive central rune socket. The object should look heavy but movable, like a puzzle block that can be pushed after charging. Game-ready stylized asset, simple materials, gray-brown stone, cyan emissive strip, small bronze accent. No texture noise, no dense cracks, no rubble around the base, no realistic sculpting, no organic rock shape.
