The Caretakers of the Imaginarium Geographica are at war. The last stones from the Keep of Time are falling, and, at the request of an old enemy, a new tower is being built in our world. The old enemy is the Winter King's Shadow, and he wields a terrible weapon - the Spear of Destiny - which can be used to command the shadows of anyone it touches. . . including the protectors of the Archipelago, the dragons. The Shadow King returns to the Archipelago using the ship, the Iron Dragon, and enlists an unstoppable army of Dragon Shadows. . . While WWII rages in our world, all the caretakers, both past and present, must come together to save the Archipelago. All hope lies with a small group of companions, along with mythical knight, Don Quixote, who must sail beyond the very ends of the Archipelago in search of a broken sword, and the only being alive who can repair it: a scholar, who, once upon a time, was called Madoc.
