Pori Peninsula War or also known as Jakti-Metslyvania War is a war fought between Jakti and Metslyvania that is underway by 3101 and ended in 3123. It was the most widespread war in the Metslyvania history, with more than 100 million people serving in military units. In a state of "total war", the major participants placed their entire economic, industrial, and scientific capabilities at the service of the war effort, erasing the distinction between civilian and military resources. Marked by significant events involving the mass death of civilians, including the Newburg Massacre and the atomic bombing of Husson and Telana, it resulted in 50 million fatalities. These deaths make Jakti-Metslyvania War by far the deadliest conflict in all of Metslyvania History.
