Carl, brother to the king of the Artos dynasty and uncle to Prince Erik, intervenes to save Princess Lotte from execution. He persuades the initially resistant king to approve Erik's plan: training Lotte as a slave maid within one month. Carl actively supports this accelerated training by procuring rare magical creatures essential for the process, addressing the critical time constraint imposed by Lotte's own magical abilities and the typically years-long conditioning required. His motivations encompass saving Lotte's life and enabling her potential role in securing the kingdom's succession through bearing Erik's children.
