In the 31st and 32nd centuries, the Temporal Integrity Commission tries to fix various timelines while maintaining others. During the 2150s, they sent an operative, Richard Daniels, to the NX-01 Enterprise. Rick was also sent to the Mirror Universe where he made more than a passing acquaintance with the Empress Hoshi Sato. As a result, Rick has fathered a temporally paradoxical child, Jun Sato, heir to the throne.
No one can know about Jun's parentage, so the TIC keeps it quiet and not even everyone who works there knows. In the meantime, a new threat emerges. But first, the background of the characters.
