An imposing knight stands clad in elaborate amethyst armor, devoid of weapon, shield, or cape. The armor pieces are sculpted from deep purple crystalline formations, exhibiting sharp, faceted edges that reflect light with a vibrant, jewel-like sparkle. Each plate seamlessly interlocks, forming a rigid, powerful silhouette. The surface gleams with a polished, cool touch, revealing internal striations of varying violet hues, emphasizing its precious, mineral composition.
