Prologue: See you soon, my Prince.

Almost an entire year has passed since the events of the War of Two Worlds, and Arthur has returned home to his grandparent's house, home of the Minimoys. The sky is looking clear, the telescope has been repaired, and even his father is allowing him to visit his tooth-sized friends. But on the night of the tenth moon, a mysterious professor arrives at the Suchot household, determined to expose the Minimoys and their magic to the world. Reunited with the cunning Max, the redeemed Darkos, the hilarious Betamache and the beautiful Princess Selenia, Arthur must find the strength to fight against an enemy capable of turning his world upside down forever.
