KBY, officially named the Kortorisan-BlyDonian-Yulairian Joined Forced, is a quickly formed military alliance made up from three civilizations in the Appearence: the BlyDonian, Kortorisan, and Yulairian Civilizations. It was formed when the Trade Emergency Coalition broke the Kortorisan-TEC peace treaty in 2010, and was formed in order to speed up the restoration of peace as part of the KBY-TEC war.
Their joined effort in the war only lasted 6 days, and in that time hardly any battles commensed. The organization would then cease to be unofficially and casually recognzied, and didn't meet.
Then, however, on the 12th of May, 2011, the Yulairian Civilization was destroyed, removing it from KBY. Thus; it now stands as a one-party alliance.
