A high-quality ore used by Skybuilders, featuring a lustrous, metallic surface with a deep blue hue and subtle glowing veins that pulse with aetheric energy. The ore is roughly the size of a human fist, with jagged, angular edges that suggest it was recently mined. Its surface is slightly rough to the touch, with occasional smooth patches where it has been naturally polished by environmental elements. The glow from the veins is more pronounced in darker environments, casting a soft blue light on nearby surfaces.
