Born in a one-room hut in the snowy tundra of Björju Island on the 2nd of Emberis, 1487, Skuldr Thorason spent his earliest years in the wilds. White Ursinefolk typically birth twins, but Skuldr's unnamed twin sibling was stillborn. While he was the only child of his mother, Thora Toklosdottir, Skuldr did have a few half-siblings through his father Nanook Tuqsun, many of whom he never met. In his earliest years, he and his parents moved somewhat frequently due to the scarcity of resources on Björju. When he was almost 2 years old, his family properly settled some distance outside of the city of Nylokni.
As young as 5 years old, Skuldr's parents began to teach him the skills necessary to survive in the frigid lands they called home. These skills included hunting, fishing, and hut-building. Thora, his mother, also taught Skuldr how to prepare the food he collected and create delicious meals with little ingredients. Despite this being at such a young age, Skuldr remembers these moments as some of his fondest memories. In contrast to his mother, Skuldr's father Nanook was much more absent in his life. As he was the founder and leader of the Sulijaq, a separatist group that was seeking to dismantle the Kingdom of Kalvete, Nanook was frequently away from home for long periods of time. When he was present, he focused on teaching his young cub how to properly wield a weapon and fight. Nanook was much harsher on Skuldr than Thora ever was, believing that the verbal abuse and rare physical punishment would prepare him for the difficulties of life. Their differing parental strategies caused Nanook and Thora to argue quite frequently, further affecting Skuldr's childhood development.
On the 21st of Perswyn, 1494, Skuldr's childhood came to an abrupt end. As his skills with hunting and combat had been improving, Nanook planned to have Skuldr join him in the Sulijaq and their rebellion. He had begun an effort to instill his ideals into his son whenever he was home, but Thora, who was a proud citizen of Kalvete, often worked to undo this when Nanook was gone. The 21st was one of the rare occasions where both his parents were present, and their differing views on the Kingdom and the role Skuldr should play in the Sulijaq led to a heated argument between the two of them. As Nanook had been drinking heavily, this argument turned into violence. In his drunken rage, Nanook slit Thora's throat and killed her. The trauma of witnessing such an event birthed a great fury inside Skuldr, who was only 7 years old at the time. This fury took two forms: A desire for vengeance against Nanook, and a sense of self-hatred for being too weak to protect his mother.
