A valkyrie who has been asleep for years, imprisoned by her own armor. When Sigurth frees her, she tells him her story. Two kings were fighting, Agnar and Hjalm-Gunnar, and Odin had promised victory Hjalm-Gunnar. Sigerdrifa killed Hjalm-Gunnar in battle, and in retaliation Odin shot her with a sleep thorn ( Crawford 253). She proceeds to give Sigurth advice on how to act and behave in the world in return for her freeing him.
