Ægir

In Norse mythology, Aegir is the god of the seas. He is the king of all the oceans. Aegir was feared by sailors, for this god would sink ships and take cargo. Aegir was worshiped by sailors who were afraid of him and sailors who were not. He has a wife named Ran and with her, they had nine daughters called the "waves".
