Input: One attested nickname of this figure is Vindhler which means "wind shelter". Hallinskidi is another nickname of this figure, which may mean "bent stick," and also refers to rams. The man who slept between Ai and Edda to create serfs and Afi and Amma to create herdsmen is said to be this figure, according to the prose introduction to a poem found only in the Codex Wormianus, the Rigsthula. That echoes the suggestion in the first lines of the Voluspa that all races are kinsmen of this figure. In the Husdrapa he fights with another god in the form of a seal in order to retrieve the necklace Brisingamen. This son of nine mothers is destined to be the last of the Aesir to die at Ragnarok where he will kill and be killed by Loki. In addition to the horse Gulltoppr, he is the owner of Gjallarhorn which he will sound to assemble the Aesir. For 10 points, name this Norse god who guards Bifrost, the rainbow bridge to Asgard.
