A seamless blend of futuristic technology and primordial sorcery, it boasts a sleek blade of shadowed obsidian, seeming to swallow light entirely, with vibrant indigo veins coursing through its core. Its hilt features intricate celestial designs, echoing the dance of dying galaxies, and cradles a levitating orb of dark energy that emits a mysterious gravitational pull. When summoned, the weapon warps the fabric of space, creating undulating distortions in reality, and with a single swing, it can open miniature black holes, devouring all in its trajectory. A formidable creation of cosmic supremacy, it commands awe and terror from the divine and mortal realms alike.
