The Sentient Shard is a high-detail, organic-looking fragment with a sleek, asymmetrical shape that appears both alien and biomechanical. Its surface is smooth with a metallic sheen, featuring intricate, glowing patterns that pulse with a vibrant, luminous energy, suggesting a living or sentient origin. The shard's edges are sharp and angular, with a crystalline structure that refracts light, giving it an iridescent finish that shifts between deep blues and purples.
