Muse

Muse is a shapeshifter whose ability is limited to changing into inanimate objects. She is a reluctant henchmen and only obeys orders so that she is not punished. She is never successful on her missions and is punished anyway, however. Noelle and the others never seem to notice that she is around which is partially due to her shapeshifting ability and partly due to her ineptness at interfering. She is madly in love with Eros and will doing anything he orders. She can be a bit of a crybaby at some points.
