In T.C. -80 (80 years before the Trial Century) the first colonization began. Many facilities were constructed to handle the population, including several cities. Colonization appeared to be successful. However, as the colony began to expand the humans encountered a new form of alien life known as the Akrid. The Akrid were clearly a hostile force but the colonists did not possess strong enough weapons to fight the Akrid. They were forced to retreat from E.D.N. III. During the fighting, humanity discovered a new type of energy source, Thermal Energy, in the bodies of the Akrid.
