Standard Earth Year (SEY): 2546 is best known for the end of the 第一次塔維因戰爭, a decisive victory for the UPE（地球行星聯合國 ） that prompts the capture and colonization of the 塔維因 homeworld of Kaleeth (renamed Jalan) and its system Kaleeth'ala (renamed Elysium). Idris IV is renamed Locke in honor of the leader of The Greys.
In February, there is an explosion at the Tram branch of the TDD, killing 700. The 地球聯合帝國督導局 connects it to the same 希安 bomb components used in the Atrocity at Jata in 2545. Over the following weeks, fear festers in the UPE as four more terrorist bombings occur, killing hundreds more. 公民s vote in favor of replacing the Tribunal with a single Prime Citizen, then in an emergency election on 2546-12-15, promptly select Ivar Messer for the position.
