In the Old Norse record, Ægir hosts the gods in his halls and is associated with brewing ale. Ægir is attested as married to a goddess, Rán, who also personifies the sea, and together the two produced daughters who personify waves, the Nine Daughters of Ægir and Rán, and Ægir's son is Snær, personified snow.
