The eldest son, Olaf III, and the youngest daughter, Princess Vanessa.
After the death of their father, Waldemar IV, Olaf III, who was still a minor at the time, became the King of Alborg, with Margaret I as the regent, effectively becoming the true ruler of Alborg.
After the death of her husband, Haakon VI, she helped Olaf III inherit the throne of Gothenburg.
Years later, her son Olaf III died unexpectedly, and she was then appointed as the "full authority ruler" of Alborg and Gothenburg.
Subsequently, Margaret I spent six years defeating her arch-enemy Albrecht, conquering the Oslo Kingdom, and was acclaimed as the King of Oslo, thus becoming the Queen of the Kalmar Union of Three Nations.
Without question, she was the founder of the royal authority of the three kingdoms, a politician and military strategist of great wisdom, far superior to her father, husband, and son.
With the highly centralized Northern Codex, she held supreme authority in the three countries.
