Imagine a pet that is a small panther cub infused with the cosmos. Its fur is a deep, velvety black, but as it moves, its coat shimmers with swirling galaxies, constellations, and distant stars. The creature’s eyes glow like twin moons, shifting between silver and deep purple, and its claws leave faint traces of stardust wherever it walks. Its body moves with feline grace, but when it runs, it appears to phase in and out of reality, leaving behind trails of nebula-like mist. The creature is both mysterious and majestic, a loyal companion to any star-gazing mage.
