Fate Apocrypha: Zugzwang
The Zugzwang were tasked with investigating and dealing with any outsider who seeks information about the Fortress of Millennia or Trifas. Utilizing their information network involving relatives of the Yggdmillenia across the world, they were prepared to complete their task within twenty-four hours in any part of the world. The Zugzwang tracked Reika Rikudou to her appartment building after she called the Romanian government’s tourist bureau and asked about the Fortress of Millennia in Trifas, and requested to contact its owner to negotiate having a tour there. Unaware that Reiku was hoping to lure the Black Faction intro a trap, the Zugzwang found no trace of Boundry Fields, magecratf, or disordered prana and disabled the survilence cameras. After breaching Reika's appartment from multiple directions, the Pawns were swiftly eliminated by Assassin of Black and Assassin declared that King will be killed by her mother. King attacked a shadowy figure with his blowpibe and dagger, mistaking it for Assassin's master, only to find the hanged corpse of Hyouma Sagara which also had a cord around its feet made to detach from the ceiling after some time passed. After a cell-phone sewn to Sagara’s abdomen rang, King took it and smashed it on the floor with his foot in anger, only for Reika to come from behind him and declare "checkmate" before cutting his trachea with a large razor. King slipped on Sagara's entrails in a final and desperate attempt to retaliate.
