Freyja's Falcon Cloak
Freyja's falcon cloak, also called the feather cloak or fjaðrhamr, is a garment of feathers that lets its wearer fly in the shape of a falcon. In the Prose Edda the cloak is kept by the goddess Freyja and lent out when the gods need swift flight: Loki borrows it to search for the goddess Iðunn after the giant Þjazi carries her off, and later uses it to pursue Þjazi, who had taken the shape of an eagle, back to the walls of Asgard where the gods kill him. In the poem Þrymskviða, Freyja's cloak is likewise the means by which Loki flies out to steal back the hammer Mjölnir. Shape-shifting feather
