The Unification Wars is the name of a number of conflicts fought at the end of the Age of Strife. They were spearheaded by The Emperor in his attempt at reunifying the shattered tribes and nations on Terra. His intentions were to reforge the shattered remnants of Man and create an Imperium that would bring about a Great Crusade to bring order to the galaxy.
During this turbulent time, the Emperor led his Thunder Warriors in a series of campaigns against all other warlords on Old Earth. A number of military formations were created as a result some of which still serve in the Imperial Army. One of the last of the tyranical warlords to fall during the closing days of the war was Dalmoth Kyn.
