The Khaydarin Shard is a radiant, crystalline artifact with a sleek, geometric structure, featuring sharp, angular edges and a luminous core that pulses with a soft blue energy. Its surface is smooth and polished, with intricate Protoss hieroglyphs etched into its facets, glowing faintly with the same energy as its core. The shard emits a subtle hum and a gentle light, suggesting its powerful psionic properties.
