Southern kingdoms
Formerly
The current regent of the Winter Kingdom. Before his coronation, the Winter Prince wished for his country and the other Southern kingdoms to be free from the Central kingdoms who economically controls their nations by giving them financial aid in exchange for continuing fighting the demons. Knowing such aid is unreliable and cannot last forever, he was grateful for the Crimson Scholar in helping his nation prosper to be economically independent from Central. After his father was killed during the first disastrous expedition to reclaim Aurora Island, he assumed the throne to become the new Winter King and appointed Female Knight as the new Commander of the second expedition to reclaim the island. Thanks to her, Crimson Scholar and Hero, Aurora Island is reclaimed from the demons. To further help the South, he forms an economic pact with the Iron and Ice Kingdoms. After the Central Kingdoms and church brands Crimson Scholar a heretic in an attempt to stop the South from becoming economically independent, the Winter King offers his support and protection to her and stand up against the Central.
The original Winter King, he was killed by South Arctic General during the failed Aurora Island Expedition in order to buy time for the survivors to escape.
Queen of the Ice Kingdom.
King of the Iron Kingdom.
King of the White Night Kingdom. Unlike his Southern counterparts, which end up adopting the improvements offered by Crimson Scholar, he chooses to align with the Central kingdoms instead. Arrogant and uncaring, he refuse to take responsibility when his attempt to reclaim Aurora Island fails which led to many deaths, including the first Winter King who he tries to blame on his failure. After the rest of the Southern leaders call out on his behavior, he gives command of the next Aurora Island expedition to the new Winter King to see if he can do better but much to his anger, the Winter King succeeds in what he failed to do. With his kingdom being left out the economic pact between the Winter, Ice and Iron kingdoms, White Night King becomes jealous and swears revenge on the other Southern nations.
