For 10 points, identify this son of Njord, the Vanir fertility god.
Two of this god's servants are thought to be associated with bread-making and are named Byggvir and Beyla. One text claims that he was succeeded by his mortal son Fjolnir as the ruler of Uppsala, while he meets his future wife, a daughter of Aurboda and Gymir, at the grove of Barri. This deity is said to have received Alfheim as a tooth-gift. He kills the giant Beli with the "horn of a hart" but is unarmed at Ragnarok, where he is killed by Surt; both of those events occur after he gives his magic sword to his servant Skirnir in order to woo Gerd. He rides the golden boar Gullinbursti and owns the folding ship Skidbladnir. For 10 points, identify this son of Njord, the Vanir fertility god.
