Sweyn (スヴェン, Suven) was the Danish king who managed to conquer almost the entirety of England and Wales, all the while keeping control of his more northern kingdoms. His wit, ferocity, ruthlessness and battle tactics kept everything under water-tight control.
King Sweyn is an old man with multiple skin problems. Although none of them are named, they are obvious. He is missing several teeth, has rather droopy features and many deep-set wrinkles; however, he's managed to keep a full head of black hair, not marred by any white. His beard is usually kept in two opposing spikes, and smoothed out, while his hair remains curly and unruly. Upon his head, he has a crown which he blames for becoming obsessed with power. This crown varies as he is both King of Danes and English; meaning he has 2 different crowns.
Sweyn is known for his wit, ferocity, ruthlessness and battle tactics, which kept everything under his rule in water-tight control. His ruthlessness and battle tactics are shown when he refused to adhere to his Jomsviking Commander Floki to withdraw from England. Instead, he proposed they rest until summer so the soldiers could fight better than in the harsh winter elements.
