The Perpetual Regulator (Source Alpha) is a jewel of impossible engineering, an ovoid artifact no larger than a polished agate. Its seamless shell is composed of a dark, crystalline quantum alloy, yet from within, a rhythmic azure glow emanates, pulsing gently like a captured star. This brilliant luminescence is the visible manifestation of its infinite energy conversion. Where its nano-fibrous connectors interface with the host's vessels, the azure light transitions into threads of liquid silver, tracing the flow of synthesized energy. The device appears impossibly polished and constantly shines, exuding an ethereal light that makes it feel less like mere technology and more like a contained fragment of cosmic power.
