Ægir is a giant and a king of the sea in Norse mythology. He seems to be a personification of the power of the ocean. He was also known for hosting elaborate parties for the gods. In Snorri Sturluson's Skáldskaparmál, Ægir is identified with Gymir and Hlér who lived on the isle of Hlésey. The prose header of Lokasenna states that his hall is a place of sanctuary lit with bright gold and where the beer pours itself.
In Norse Mythology, Ægir and his daughters brew ale in a large pot.

While many versions of myths portray him as a jotun, it is curious that many do not. In some texts, he is referred to as something older than the jotun, and his origins are not really explained.
