The Mothership Core is a spherical, high-tech Protoss unit with a diameter of approximately 5 meters, featuring a sleek, metallic outer shell with glowing blue energy circuits running across its surface. The core is encased in a transparent, crystalline energy field that pulsates softly, indicating its active state. At its center, a bright, blue-white energy core emits a radiant glow, surrounded by intricate, floating Protoss hieroglyphs that rotate slowly, adding to its mystical and advanced appearance. The surface is smooth with a polished finish, reflecting light subtly, and the overall design is symmetrical with a complex, yet elegant structure that emphasizes its importance and power.
