When Zaiyorus was born in Lake Weißälersee (Hanseti-Ruska), he was taken to an orphanage as soon as possible because his parents had no money. Zaiyorus was adopted by his grandfather, with whom he lived happily until he was ambushed by cultists in the night. Through the window, he saw the grandfather knock out five of them, but he died like a hero. When Zaiyorus had to get back to an orphanage again, Gregorius, who was 3 years younger, became his brother. After Zaiyorus got a job harvesting medicine plants at 15 years old, he bought food for him and his brother Gregorious, and they saved up to buy a house and tools. After robbing another farm, they bought a house and got chickens. In his view, Gregorius is more intelligent than him, so he paid for Gregorius' education. While he was picking potatoes from the little farm, one guy named Robert stared at him. Zaiyorus told Robert he wants to work for him, but Gregorius says "As long as we can produce it, it doesn't make any sense to work for others." So Zaiyorus told Robert he wants to work for him, but they would be better off alone.
