My name is my favorite character from a book by Piers Anthony. Mare Imbrium first appeared as a minor role in Ogre, Ogre and had a major role in the following book in the Xanth series called Night Mare. She was actually a female horse (mare) who was originally had the job of giving everyone nightmares (hence the occupation of Night Mare). Then later on she turned into a daymare which is a horse giving daydreams. Imbrium means Sea of Rain (Latin I think).
