According to traditional Norse beliefs, Freya is the daughter of the sea god Njord and an unknown giant mother. Though there are conflicting reports in historical documents, there is evidence to believe that she is also wife to the god Odin, and is the one in the same with the goddess Frigga. While Odin takes many heroic dead to reside with him in Valhalla, Freya takes others to reside with her in her hall of the dead; Sessrumnir. She is also said to be the chief of the demi-goddesses, the Valkyries, who serve in both halls.
Freya is also believed to access magic with which she could prophesy and shape shift. She's most commonly illustrated to take the form of a falcon, and accompanied by gray cats.
Gold on the earth and amber in the sea are believed to have once been Freya's tears, which she shed while searching for her husband who was lost during battle. Giving the world beautiful things during her mourning is due to a glittering necklace as an emblem of the earth's fruitfulness. The winter constellation Orion was perceived by the Vikings to instead be of Freya, and Orion's Belt to be "Freya's Girdle".
There are also writings that suggest Freya had golden hair that blooms with flowers and white arms that light up the underworld when she visits.Portrait of Hiccup as a Buff Young Man", the Dragon Riders are trapped inside an ice cave trying to solve one of the clues to find the treasure of Hamish II.

- "Doest thou Fishlegs Ingerman, child of Odin, takest Ruffnut Eugene Thorston, daughter of Freya, as your betrothed?"

As the goddess of beauty and fertility, it's sensible that Freya would be referenced during a wedding ceremony, specifically as the birthgiver of the bride.

They say they were given the task of caring for baby Razorwhips by Freya herself centuries earlier. To celebrate the end of nesting season, they hold a feast they call the "Feast of Freya", at which they serve a "sacred stew" that has taken days to prepare.
