After pushing a broom for centuries, Merlin's apprentice, Douxie, springs into action when the great sorcerer asks him to find the Guardians of Arcadia.

With the future at stake, Douxie and Claire cling to the hope that Arthur and Morgana can reconcile. Meanwhile, humans are hunting trolls in the woods.

The race is on to find the Genesis Seals as Douxie and Archie look for clues in a notorious dragon's lair. Claire searches the shadows for Jim's soul.

The Arcane Order pushes Douxie to make an impossible choice: save his friends ... or save the planet. Which will he pick? Only time will tell.
