In the story of the binding of the wolf Fenrir, after their previous attempts had failed, the Æsir sent Skírnir to the land of the dwarfs to have them make the unbreakable fetter Gleipnir. The gods then went out upon the lake called Ámsvartnir, to the island of Lyngvi, and summoned Fenrir to them. They tricked the wolf into being bound with Gleipnir and there he shall lie until the time of Ragnarök.
