Kristoff Stonelaw resided on the planet of Vernet, being the offspring of Arn and Emmi Stonelaw, sibling to Yuri Stonelaw, and the adopted sibling of Mair Koda. Upon the arrival of the Galactic Empire to Vernet, and their subsequent construction of a base there, Kristoff was drafted into military service and commenced his instruction to become a soldier. Throughout his training period, Kristoff underwent indoctrination, absorbing the Empire's biased information primarily via the consumption of food laced with drugs and through concealed persuasive techniques. In a rescue attempt by Mair Koda and Yuri, they discovered Kristoff's reluctance to depart, and his willingness to betray his brother to his commanding officer. Consequently, Koda and Yuri were compelled to escape Vernet following the unsuccessful attempt to retrieve their brother.
