The Dark Pylon is a towering, obsidian-like structure with a sleek, futuristic design, featuring sharp angular edges and a glowing purple energy core at its center. Its surface is smooth and highly reflective, with intricate Protoss hieroglyphs etched into its base, emitting a faint luminescence. The pylon's energy core pulses rhythmically, casting dynamic shadows and light effects that enhance its ominous presence.
