Sif
Thor’s wife and Ullr’s mother; Loki cutting her hair sets the treasures of the gods in motion.

Overview
Sif appears in Skaldskaparmal as Thor’s wife, Ullr’s mother and a fair-haired goddess. When Loki cuts off her hair, Thor forces him to make amends, and that pressure begins the dwarf-crafted treasures episode. She is not the combat protagonist, but she is the harmed figure and household centre that starts the treasure narrative.
