The Ancient Relic Crystal Shard is a medium-sized, asymmetrical fragment of a once-magnificent crystal, featuring sharp, angular edges and a complex, geometric internal structure that glows faintly with a pulsating blue light. Its surface is smooth yet slightly weathered, with intricate, naturally-formed runes that shimmer when exposed to light. The shard's core emits a soft, ethereal glow, suggesting it contains residual magical energy.
