It features a central, circular core surrounded by floating, geometric panels that emit a soft, blue glow, symbolizing its connection to the Khala. The structure is adorned with golden, ornate engravings that highlight its importance in Protoss society, and its surface is smooth with a slightly reflective finish, giving it a pristine yet powerful appearance.
