Long after the death of King Arthur, the sorcerer Merlin escaped from the cave of enchantment on Druid Island after having been held prisoner by the evil witch, Morgana. With the help of the goddess Athena, Merlin was able to trick Morgana and seal her within the cave where he had languished for so long. Old and with his health broken, Merlin took his infant son, Thomas, to Shetland's Rock to be raised by a wealthy family knowing that, after his death, the goddess would keep watch over the boy. As he grew, having inherited his father's magical powers, Thomas learned the ways of the Druid and became the protector of Druid Island. For over 30 years, Morgana attempted to free herself so she could continue her evil ways. Unable to stop what he knew would be her inevitable escape Thomas sought the help of a young boy, David, whose father was the Druid's childhood friend. Through a series of harrowing events and in a variety of strange places, the youngster was successful in obtaining the powerful Druid's Egg and used it to destroy the witch. Thomas felt that peace would be restored to Druid's Island, but he was mistaken for the world still housed many strange creatures that sought revenge for the death of the witch, and who wanted to see both the boy and Merlin's son destroyed. Druid Island 2, The Book Of Spells, took up the story of the Druid wizard and David as they once more faced the monsters and demons that threatened the Island and the entire world. Created by the old gods, The Book of Spells contained secrets that could provide world domination for any who learned what was written on those pages. Able to keep the Book out of the grasp of the vampire, Count Valcord, David, with the god Poseidon's assistance, ensured that the book would never fall into evil hands. Told by an ancient Oracle that David was destined to replace him, the god relinquished the Trident with which he controlled the seas and left this world. In Druid Island 3, The Fate of Atlantis, David must come to grips with the fact that his sojourn into the mystical world has widened and has created new enemies, including the vampire. The teen finds his time split between his life with his family, Druid Island and the realm of the sea. Aware of it all, Thomas worries about his young ward and his own ability to keep him safe.
