Shadow Dragons

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.
