Year 2145- The end of Halcon Incident makes more united post IV world War Earth,even that some people still feared use of satelites as mean of controling any crisis situation, second World summit takes place some months later in near end of the year and Whole world unites as stronger. This year on date of 22 December of 2145 is also the date of beggining of Earth Confederation, and leading City is placed as Olympus City showed as example of unity when Halcon incident happened worldwide.
Year 2147- Two years later Poseidon Industries, the tech company aligned with Halcon Incident, happening two years before, on verge of nonexistence makes revolutionary tech called Omnitools what are better versions of their earlier product called Connexus. The thing before worldwide use was been tested for any code what would do known incident before it allowyance to Civil use, but all tests ended green and product was released into all cities of Confederation, making it wanted tech product beacuse of its capabilities of portable computer and well storage , also military versions was outfitted with some military code only, and one melee weapon called OmniBlade in it.
Year 2148- To protect the Confederation from Inside and Outside, Administrator of Olympus City and Confederation Athena makes an new division of Army called Cerberus Organization, this one have an absolute law in doing of some of things but it still stays in control of Administrator, and she calls onto Administration of Organization one of Olympus E.S.W.A.T commanders what been known to be in two incidents, one in 2144 and one in 2145, and that been one of skilled Cyborgs of that Division.
