Dracs

In Arles, an area in South France, the dracs are said to sometimes take the forms of golden rings or cups floating on rivers, and when bathers try to take these the dracs seize them and drag them to the river bottom, where they usually eat them. They can also take on human form, and live in the caverns of the rivers. Sometimes they abduct suckling women to act as wet nurses for them, and when these women return after seven years, they are unharmed by can hardly be recognized. These women will be able to see them if they rub the grease of the dracs' food into their eyes, but if the dracs discover they have done this, they will promptly blind the woman in whichever eye has this power of second sight.
