Kai Krieger / Kyger
Youngest Son of Artix in the Deadtech Future
Kai Krieger, usually called Kyger, is the youngest of Artix’s children in the Deadtech future. Frightened by the invasion, he longs to be brave like Stellaria and Asherion and worries about his missing friends. Stellaria has tried to keep him safe because he is young, but asks the Hero to train him, with Artix guiding them through his axe. Kyger learns compassion for escaped undead villagers who want to live in peace. After pulling the Blinding Light of Destiny from the stone, he joins his siblings against the Technolich despite the slim chance of success.
