What happened to Kaine is the Garda detained him for finding Lumi in his camp, he was punished for her running away, Yordan decided the appropriate yet still as lenient as he could comfortably allow punishment would be a temporary banishment from Vallaki and all of its surrounding associated lands, and then, Kaine found himself marched out of town at the crack of the next dawn naked and in irons. As soon as he was uncuffed at the border and dressed himself he found some water as the Garda left,drank it and was brutally murdered by the Harbinger who was less than pleased his foe was still living. His wife was as powerless to do anything about it as he was. Kaine's body was severely mutilated and as is the Harbinger's usual procedure, stripped of gold and weapons then hidden in a very hard to find place.
