Meanwhile, in a quiet village, Frans the schoolteacher invents incredible stories of perilous deeds, shipwrecks, desert islands, and haunted castles to entertain his pupils, in which he is the hero. Then one stormy evening, a mysterious letter blows onto his doormat, summoning him to a meeting.

He will learn the secret of the Seven Ways.
He will find seven allies.
And he will make a fearsome enemy.
The adventure has begun...
