Gleipnir
A magical fetter, smooth like silk yet strong enough to bind Fenrir.

Overview
Gleipnir is the point where Fenrir's story truly turns. The gods first bring out two iron fetters to test the wolf's strength, but every break only shows them more clearly that ordinary iron cannot hold him. Then Gleipnir is brought before him. It looks small and soft, almost unlike a restraint, yet it comes from dwarven hands and is made from impossible things. By Gylfaginning 34, the danger no longer lies only in the band itself but in the gods asking Fenrir to trust them. He senses deceit and refuses to be bound lightly; only when Tyr places his hand in the wolf's mouth does the trial truly begin.
Key facts
Made from six impossible things
