Viking berserkers were fierce warriors known for their frenzied battle rage, believed to embody the spirit of animals, particularly bears or wolves, during combat. In Norse lore, they were thought to enter a trance-like state, drawing strength from Odin and invoking divine protection, which allowed them to fight with unmatched ferocity and resilience. Berserkers played a significant role in Viking raids and battles, symbolizing the raw, untamed aspects of warfare and the connection between strength, madness, and the divine.
