The campaign started as a series of displays on the Niwray Border, but escalated in the Jimbern Regions including the Lornbiv Village. Lornak forces continued into the Jamholt Region, but overwhelmed the Tralesta led by Mesabb. At the time, there were thought to be no survivors, but there were actually five. They devised a plan to retaliate and chose Yuta to carry it out. She carried a microvirus and systematically sought out the Lornak clan members and infected them.
