The FAIRY Queen is a character from William Shakespeare's play A Midsummer Night's Dream. She is the queen of the fairies and is known by three different names: Una, Titania, and Mab. Una is derived from the Latin word for 'ONE' and is used to refer to her as the sole FAIRY queen. Titania is a variation of the Greek goddess of the dawn, Eos, and is used to refer to her as a beautiful and powerful figure. Mab is derived from the Celtic word for 'FAIRY' and is used to refer to her as a magical being.
