Loki told another story about Thor—about Thor and Thrym, a foolish Giant who had some clever tricks. Loki and Thor had been at this Giant's house. He had made a feast for them, and Thor had been careless.

Then, when they were far from Jötunheim, Thor realized he was missing Miölnir, the hammer that protected Asgard and helped the Gods. He couldn't remember how or where he had misplaced it. Loki thought of Thrym, that foolish Giant who still had some clever tricks. Thor, who had lost the hammer he swore never to let out of his sight, didn't know what to do.

But Loki thought it might be worth checking if Thrym knew anything about it. He went first to Asgard. He hurried across the Rainbow Bridge and passed Heimdall without speaking. He didn't dare tell any of the Dwellers in Asgard about Thor's loss. He spoke to no one until he reached Frigga's palace.

To Frigga, he said, "You must lend me your falcon dress so I can fly to Thrym's place and find out if he knows where Miölnir is."
