During the Great North War, Kryos served as a Captain in the Bethaven Militia Force infrom 646645 until its dissolution in 646. Bethaven later commended Kryos on his organizational skills, although the militia never saw action. In 647, Kryos was appointed as Judge of Bethaven, where he established precedents in several notable cases, including three land dispute cases, eight contract dispute cases, and a murder trial. Although young, his legal acumen and fair judgments earned him high praise from his peers. In 648, Kryos inherited Kryos House, the ancestral home of his family, along with a substantial fortune. He donated a large portion of his wealth to both local and national charities, established an orphanage in his home, and allowed local farmers to graze their herds on his land. Kryos House remains a farm, dedicated to the economic and environmental use of resources.
