A mysterious time travel event known as the Verge had brought thousands of people from across all of history to New York City. Vikings, Samurai, Romans, Mayans, Cavemen, and thousands of others all live in a vast and turbulent melting pot. Connie Liu, an NYPD Detective, investigates the murder of three Samurai, a case which threatens to turn the divisions in the city into all out war.
As the Vikings raid and pillage across the city in retribution for Eirik's death, Connie begins to suspect that there's much more to this case. She takes Lucy and Ravi, the only two police officers she trusts, to Satsuma Temple, the mysterious sanctuary for Samurai refugees.
