In the land of Asgard lived the Thunder God, Thor with his mighty hammer Mjollnir. But one day Thor awoke to find his hammer stolen by the Giants who lived on Jotunheim.
The only way to get Mjollnir back was to wed the king on the giants to Freya, goddess of love and beauty. That didn't sit well with her so Thor and Loki came up with a plan.
Thor would dress as Freya and go to the wedding to get back his hammer and come back to Asgard. Being as the Giant had never seen Freya, Thor took up a form of a woman and dawned a white dress and set out for Jotunheim.
Thor arrived with Loki to Jotunheim and was introduced as Freya. He then was taken away to a room to wait for his "wedding".
As custom, Thrym, the giant, called for the hammer to hallow their union, But as soon as Mjollnir was laid in Thor's lap, he grabbed the handle and slew first Thrym ten all the guest before returning to Asgard.
In the end Thor returned to Asgard with Mjollnir and back in his own clothing no longer needing the disguise of Freya, all was right in his eyes until something new happened
