Ægir's daughters, known as the Norns, are figures from Norse mythology who personify the waves of the sea. They are often depicted as beautiful maidens who serve their father, Ægir, the god of the ocean. The daughters are named Hynm, Bil, and Dúfa, and they are associated with the natural forces of the sea. In the myths, Ægir's daughters are sometimes portrayed as serving drinks to the gods during feasts held in their father's hall. Their presence highlights the connection between the sea and the divine, emphasizing the importance of water in Norse culture and its role in the lives of the gods and humans alike.
