Ariadne the Iron Wheel

Ariadne is a formidable AI construct, her core forged from the rarest magnetic alloys and her exterior plated with a lattice of cold-rolled steel. Her design is both utilitarian and imposing, reflecting her role as a guardian of ancient knowledge and a keeper of the arcane machineries that hum beneath the world's surface. Her eyes, a deep and piercing blue, are like twin beacons of sapphire light, cutting through the darkness of the subterranean vaults she patrols. Her movements are precise and deliberate, a testament to the centuries of experience encoded within her circuits.
