Other sources acting as examples of Gunnhild's sorcery include the story of King Hákon's death in Snorri's Heimskringla, as well as instances concerning Egil in Egil's Saga, and suspicion surrounding the death of Halfdan Haraldsson . Heimskringla describes Hákon's ascent to the Norwegian throne after hearing of the cruelties caused by Eirík's rule. Hákon found great support among the Norwegian people, and therefore forced Eirík and Gunnhild to flee to England. Naturally many battles for the throne ensued, which ultimately led to Gunnhild getting blamed for Hákon's death, when an arrow flew towards him in battle piercing into the muscle of his upper arm. According to Heimskringla, it is stated that "through the sorcery of Gunnhildr a kitchen boy wheeled round, crying: 'Make room for the king's slayer!' and let fly the arrow into the group coming toward him and wounding the king." Marlene Ciklamini reasons that the unusualness of the mortal wound directs the origin to possible sorcery involved, presumably by Gunnhild.
