The Secret of the Iron Mask (Das geheimnis der eisernen maske)

Description en anglais

France, centuries ago: a shadow lies over the throne. A rumour – silenced but never forgotten – tells of a man with an iron mask, hidden in the dark dungeons of an old abbey. He is said to have been no ordinary prisoner… but the true king.
Today, as descendants of the rightful heir to the throne, you are facing a historic turning point. The time has come to break the silence. You have found a secret entrance to the abbey – hidden deep beneath stone and darkness.
Your mission: find the evidence of his existence. Reveal the secret that the kingdom has unjustly kept from you. But be warned… the truth has been well hidden – and it doesn’t want to be found.
