What is "umberlee"

Umberlee is an evil sea goddess in the Faerûnian pantheon, in the fictional setting of Forgotten Realms for the Dungeons & Dragons fantasy role-playing game. In the RPG gaming literatures, she is most often worshipped by sailors or people travelling by sea, out of fear for her destructive powers. She controls the harshness of the sea and, revelling in her own power, she is not hesitant in drowning people at sea, if she so pleases.
