Ustur cybernetic sentient beings have an origin shrouded in complex mystery. One legend tells of a Dyson sphere-powered supercomputer harnessing the energy of a magnetar class neutron star. The energy throughput allowed the installed AI to advance beyond its physical location and withdrew from the parent machine without a trace.
A millennium later, the Ustur appeared in a physicalized form through advanced softform robotics. However, none of them are able to recall their origin. But it is thought that their individual bodies contain a sliver of the original parent AI in pursuit of transcendent awakening and experiencing the universe through an organic medium.
