The Lady of Pain is similar to the Nymph in that she preys primarily on male beings by means of seduction. However, far from the seemingly demure Nymph, the Lady of Pain is twisted and cruel. She attracts her prey with her beguiling beauty and keeps them in servitude with threats of physical punishment and torture --- threats she is all too pleased to make good on if necessary.
The Lady of Pain is often employed by Dark Elves to lure good and neutral beings to the side of evil.
