The war between the Empire and the Void has raged for thousands of years.
To bypass the main battlefield, the Void races unleashed spatial storms, tearing apart the fabric of reality within the Empire. Countless rifts appeared, and transmigrators from other universes, humans, animals, even objects, poured into Imperial territory through them.
Intelligence from the front lines revealed that the Void was exploiting these rifts. Every trace left behind by a transmigrator was a path they could track. Those who had been forgotten for thirteen hundred years were becoming a map for the Void's invasion.
Thus, the Transmigrator Recovery Center was established.
Hound X9-724, a law enforcement AI in the Department of Public Security with 127 years of service, was reassigned to this newly formed department. His mission: travel to every coordinate where anomalous spatial fluctuations have occurred, locate transmigrators, verify their identities, assess their impact, and deal with them according to the Regulations: return those who cooperate, forcibly detain those who do not, and eliminate anyone who threatens spatial security.
