Arn Stonelaw cultivated chorba crops on the world of Vernet. He was the husband of Emmi, and the father of two boys, named Kristoff and Yuri. In addition to his sons, Arn and Emmi took in Mair Koda, the child of a friend, into their home as foster parents. This arrangement came about after Mair's mother eloped with a Wroonian contrabandist, which left her father in a position where he could not both care for her and continue his career as a transport commander.
