👉 Halgalsor'su refers to a creature described as being of an unusual appearance in Norse mythology, resembling a spider with short arms, elongated legs, and a long tail. They were often depicted as having a body made of black and white wool, which could change color based on their mood or environment. Their eyes were usually bloodshot and would turn red upon seeing humans. The term was not widely used until the 9th century AD, but it quickly came to be associated with the Norse god Hrsgnir, who was often depicted as a giant spider-like creature.
