From the abyssal depths of a forgotten underwater metropolis, the Umbral Weaver emerges. Her form, a terrifying fusion of arachnid grace and shadow-forged might, is adorned with the remnants of ancient, broken statues. She wields a katana forged from solidified darkness, her movements a deadly dance that belies her colossal size. Electric sparks crackle around her as she prepares to unleash her breath weapon, a torrent of cosmic dust and pure terror. Legends speak of her ancient duty: to eternally seal away a primordial evil, a task she performs with an epic and majestic, yet chilling, resolve. The light shafts piercing the gloom of her domain illuminate her geometrically complex carapace, a testament to the balanced, triangular composition of her terrifying presence.
