In Norse mythology, Víðbláinn ("Wind-Blue" or "Far-Blue", combination of víð and bla) is the third heaven in the cosmology of Snorri's Gylfaginning, located above Andlang and Asgard. It will serve as a shelter and dwelling place for the souls of the dead during and after the destruction of Ragnarök.
