 The Æsir begin to grow grey and old at the disappearance of Idunn . The Æsir assemble at a thing where they ask one another when Iðunn had been seen last . The Æsir realize that the last time that Iðunn was seen was when she was going outside of Asgard with Loki , and so they have Loki arrested and brought to the thing . Loki is threatened with death and torture . Terrified , Loki says that if the goddess Freyja will lend him her " falcon shape " he will search for Iðunn in the land of Jötunheimr . Freyja lends the falcon shape to Loki , and with it he flies north to Jötunheimr . One day later , Loki arrives at Þjazi 's home . There he finds that Þjazi is out at sea in a boat , and that Iðunn is home alone . Loki turns her into a nut , holds her in his claws , and flies away with her as fast as possible .
