The Story: The Last Verse of the Hymn
At Akershus Fortress, an old and gloomy tale is told of Count Christian Rantzau, a powerful commander who died under mysterious circumstances. It is said that his hymn singing can still be heard from the fortress tower on quiet nights.
But what if the song is more than just a ghost singing? An old book found in the fortress archives suggests that Rantzau left behind a coded message. Now it is up to you to collect 12 letters – one for each puzzle you solve. Together, they will form a secret keyword that will guide you to the 13th and final hidden location. Solve the mystery before time runs out, and before his song goes silent forever!
- Experience the mighty Akershus Fortress up close.
- The puzzle require wit, logic, and cooperation.
