Zero to Hero
We look throughout the school and find hidden riddles, each one bringing us closer to the identity of the sender of the letter.
Finally we answer all of the riddles and this led us to another letter.
The letter was from Hercules! We decide that if such an important person needs our help then we shall help him. In the letter, Hercules states that we must gain knowledge of Ancient Greece in order for him to become a real god. He has given us a passport with a list of all the things we need to learn about.
We can't let him down.
