Aegir

Aegir was a fierce god of the sea in Norse and Celtic mythology. He and his wife, Ran, had nine daughters. The Norse people believed these maidens moved the waves. Sometimes Aegir would destroy ships traveling across the seas.

Sometimes, with the help of his wife, they would catch sailors with nets and take them beneath the sea into Aegir's kingdom. Saxon pirates would offer a sacrifice to Aegir for a safe journey across the sea.
