King Uther was feared by all the men, and sought the love of the fair Igraine of Cornwall, which she would have naught to do with him and that made him have grief and disappointment.
There lived a famous magician named Merlin, he was powerful enough to change his form of will and could make himself invisible. He helped King Uther with his grief and promised a son shall be born. He kept his word and had Igraine love him and make him her husband.
The King and Queen were granted a son from the magician Merlin.
