Freya is the Norse Vanir goddess of love, beauty, gold, sorcery, war, and death. She is a part of the Vanir tribe, wife of her lost husband Odur, twin sister of Frey, mother of Blitzen, Hnoss, and Gersemi, the aunt of Magnus Chase, and the ruler of Folkvanger - one of two places where Norse warriors go after death (the other being Valhalla).
Magnus and Blitz first meet Freya, when they accidentally travel to her realm - Folkvanger. There, in the hall of Sessrumnir, they meet the goddess who is revealed to be Blitz's mother.
Freya is a bright and helpful woman, very loving towards her family. However, she can quickly change her demeanor and become very intimidating, to the point where Magnus had a mental image of her riding into battle alongside the Valkyries.
When Freya's nephew, Magnus, met her for the first time in The Sword of Summer, he thought of her as the most beautiful woman he had ever seen.
She looked to be twenty-years-old and surrounded by an aura of golden radiance that serves as the source of power for the entire Folkvanger. She had long blonde hair that fell across one shoulder in a single plait, sky-blue eyes, and a smile that made Magnus' entire body heat up and instilled in him an intense longing to keep that smile fixed on him, to the extent where he would do anything she asked - even if the expense was his own life.
Freya was also dressed in a way to emphasize her beauty and her love of jewelry: a white halter top that showed off her tanned shoulders and smooth midriff, and a knee-length skirt belted with a gold braid holding a sheathed knife and a ring of keys. Around her neck was a dazzling lacework collar of gold and gems (rubies and diamonds).
