Freyja was an Asgard who bound the Draugr.
Biography[]
The Draugr couldn't be destroyed, so Freyja bound it in a grave to keep it from plaguing the village of Helgatofta. The long barrow was far from the homes of those who built it. Daniel Jackson presumed Freyja beamed them there as there was a description of a white light.
After Captain Sam Carter reinstalled the emitter crystal that was part of the Asgard technology used to bind the Draugr, SG-1 witnessed a holographic recording of her thanking those who brought the Draugr there so she could bind it forever and bid them to make merry and celebrate the rebirth of Sol.
