Aegir is a giant who personifies the ocean. He is not to be confused with Nj├Ârd, the Vanir god of the seas. Together with his wife, Ran, he rules over the oceans from his underwater halls.

Aegir is known to be a friend of the Aesir, as he hosts lavish feasts in his palace to which they are invited. During one of these feasts, he challenges Thor to get him a cauldron big enough to brew beer for satisfy the Aesir’s thirst.
