The Gordian Division

Doctor Benjamin Schröder was far from a man of action. In fact, he was a history teacher - chairman of the Castle Rock University history department - and if his life wasn't perfect, it was close. Until, that is the discussion of his star student Elzbietá Abramowski's dissertation on Operation Oz, the Pacific Allies' invasion of Vladivostok, was brutally interrupted. The psychotic episode that turned his entire world upside down struck with absolutely no warning, and it was more terrifying than anything he should have been able to imagine.

Agent Raibert Kaminski and the crew of the Transtemporal Vehicle Kleio have stumbled across a temporal implosion that has claimed two whole universes, and neither Raibert nor his crew can ­ figure out what caused this calamity, or how to stop its spread. Meanwhile, old colleagues of Raibert’s from the Antiquities Rescue Trust, together with a version of Samuel Pepys transplanted from the 17th century into the 30th, have proposed an expedition into the past. The goal? To branch the timeline by preventing the Plague of Justinian, one of the worst pandemics in human history.

It was supposed to be a routine trip for the members of the Gordian Division, both human and AI: fly out to Saturn, inspect the construction of their latest time machines, then fly back. But when the division’s top scientist and chief engineer are killed in the same freak accident, suspicions of foul play run deep. Detective Isaac Cho is sent in to investigate, but he has more on his mind than just a new case. His superiors have saddled him with an exchange officer from the neighboring Admin—Special Agent Susan Cantrell.

The Weltall Tournament’s professional VR games were supposed to be a symbol of cooperation between SysGov and its militaristic neighbor, the Admin. But that was before star Admin player Elly Sako received a death threat, written in blood next to a copy of her own severed head. The Admin’s Department of Temporal Investigation swiftly seizes control of the crime scene, and the tournament transforms into a flashpoint of charged politics and conflicting jurisdictions.

The Atlas Corporation was all set to tear apart the planet Mercury—converting its resources into a swarm of solar-collecting megastructures—when Esteban Velasco, lead Atlas engineer, is found dead from a self-inflicted gunshot wound to the head. Detective Isaac Cho and Special Agent Susan Cantrell, both eager to return to active duty despite close calls on their last case, are sent in to assess the situation. Their superiors expect a simple declaration of suicide, but Velasco’s death proves anything but typical.

After an industrial ship carrying advanced self-replicating machines explodes on its way to Mercury, analysis of the wreckage reveals it to be forty years too old. Raibert Kaminski, the Gordian Division’s top agent, and his crew on the TransTemporal Vehicle Kleio soon discover the ship had been transported to an uncharted universe, one with temporarily accelerated time. Forty years passed for the ship’s industrial machines while everyone else experienced only a few short days. Raibert is certain a powerful weapon of some nature has been built out in the unexplored reaches of the multiverse.
