Witches and Kings

The two feuding orders of witches study a prophesy that forecasts the rise of a great evil. Their reluctance to join together is accented when peace is broken, and war breaks out between two warring kingdoms. 

Prince Terrowin, the youngest son of King Grayson, is forced into exile, when the Kingdom of Dwykath attacks the Kingdom of Allisure. Magic is used in the bloody battle, signifying the evil force, controlled by Master Diablo, will use any means to win. Terrowin travels to the remote parts of the world, waiting for a time he can return to reclaim his heritage. 

As an evil force asserts control of the land, Dorian of the Dark Rose witches, and his step-sister, Ayleth of the White Rose order, conspire to fight the evil forces. They know they must reunite the two orders of witches, and need the help of Prince Terrowin, if and when he returns.
