The Government rule the Hub with an iron fist, their strict laws enforced by Derivates, humans with psionic abilities. When one of these Derivates flees her post, they send KC-847, a powerful telekinetic, to bring her back. But KC-847 soon learns he and his team are unprepared for what they find, and their mission goes awry.
Flit, a plucky teleporter, works for the Underground resistance, the last refuge for Derivates wishing to live free of the Government's control. On a routine security patrol, Flit comes across KC-847 and breaks all the rules to bring him back to the Underground.
However, KC-847's arrival brings with it a string of deadly events that threaten the safety of the Underground. Convinced the incidents are more than unfortunate coincidences, Flit refuses to fall back on a false sense of security and drags KC-847 on an investigation that will change the trajectory of Derivate-kind forever.
