As we open on Graham and his wife, we quickly see the future unfold in a story of twins separated at birth. This wasn’t a common accident, however, but instead a malicious attempt at King Graham’s confidence by the scorned Manny… who reintroduces himself as a different creature called Manannan. Spellbinding the King and Queen, Manannan talks of retribution and a future where his son will gain access to the crown. The catcher is that "his" son is actually Prince Alexander, one of the twins.
This is where our story begins, with a frantic cry and a lifelong search for Alexander. Time passes by and, after 18 years, the Prince returns to his family having been renamed Gwydion. Of course, this teenager doesn’t like either of his names, so he attempts to call himself Caduceus the Magnificent. Well, Caduceus isn’t so sure that his return to the life he was abducted from was such a good idea. He would soon learn his true fate, however, when Queen Valanice and his twin sister Rosella are taken to the middle of a labyrinth, where he has to work with his birth father to find them.
