Cringe Spectacular Episode 1
Umberlee (uhm-ber-LEE), also referred to as The Bitch Queen, was the evil sea goddess in the Faerûnian pantheon.
She was most often worshiped by sailors or people traveling by sea, out of fear of her destructive powers. She controlled the harshness of the sea while reveling in her own power and was not hesitant to drown people, if she so pleased.
Temples and Worshippers
Temples of Umberlee were few and far between, and the church was not well organized, resting on Umberlee’s chaotic nature where disputes were ruled in favor of the strongest individual. There were, however, shrines dedicated to her which were predominantly located in port cities of the Sea of Fallen Stars and in the Nelanther Isles. Here travelers by sea were sure to pay their tribute to her, and the preachings of her clerics were built upon the terrible fate that would befall any who did not bring a sacrifice to Umberlee. Clerics were available at these temples who, for a price, would travel with sailors to ensure no harm was inflicted.
Umberlee had worshipers among krakens, sahuagin and other evil sea creatures, even though a few of them worshiped her through her alias, Panzuriel.
