Umberlee

Umberlee, also called the Bitch Queen, the Queen of the Depths, and the Wavemother, is a chaotic evil deity. She's goddess of the sea, anger, and wrath in the Northern Pantheon.
Her avatar often appears as a large monstrous hybrid of woman and undersea creatures. Sailors and their loved ones primarily pray to Umberlee and make offerings for safe passage across the sea.
