The Obsidian Maw, a colossal matriarch of the void, commands the swirling energies within the black hole's maw. Her shell, a mosaic of ancient bone and humming servo-motors, pulses with a bioluminescent glow that pierces the oppressive darkness. Clad in retro glamour, she wields a tessen fan, its edges crackling with mystic battle energy. Flames lick at her form as she soars through the dust-mote-filled void, her aggressive gaze fixed on unseen foes. This dystopian ruler, a creature of bone and light, embodies the terrifying beauty of cosmic destruction, her every movement a testament to the brutal ballet of the universe.
