Forged from the very essence of the cosmos, this legendary weapon wields the power to manipulate dark matter and generate gravitational singularities. An extraordinary fusion of advanced technology and arcane magic, its sleek, obsidian blade seems to absorb the surrounding light, with luminescent purple tendrils pulsating within its core. The hilt is intricately embellished with celestial engravings resembling swirling galaxies, and it features a hovering core of shadowy energy that emanates a haunting gravitational force. Upon activation, the weapon warps the space around it, creating ripples that distort reality, and with a single strike, it can unleash miniature black holes that devour anything in their trajectory. A sublime exemplar of cosmic devastation and supremacy, it is a force of nature feared by deities and mortals alike.
