Although the sources consulted are not clear on this, the chief of the Valkyries seems to have been the goddess Freyja. She is the Norse goddess of love, fertility, and beauty, sometimes identified as the goddess of battle and death. Blond, blue-eyed, and beautiful, Freyja travels on a golden-bristled boar or in a chariot drawn by cats. She resides in the celestial realm of Folkvang. Like Odinn, she received half of those slain in battle, but since ladies go first she was allowed first choice!
Freyja possessed a magical cloak of falcon feathers that allowed her to take the shape of a falcon if she wished, making the swan maidens similar to the goddess by having “feather coats” or cloaks that enable their shape-shifting abilities and the power of flight.
