Beshaba, the Lady Doom, is the deity of accidents, bad luck, misfortune, and random mischief. She demands worship to keep her bad luck at bay. She is in a bitter rivalry with her sister, Tymora, Lady Luck.
Beshaba is revered more out of fear than out of religious faith. Her doctrine states that bad luck befalls everybody and the only way to avoid it is by worshiping her. She is renowned for being spiteful and malevolent, and her priests manipulate common folk into revering and providing for them by acting mysteriously and playing on morbid fears.
