The Secret of the Dune Guardians of Spiekeroog

"Over two hundred years ago, something vanished here that must never fall into the wrong hands. Not gold, not jewels – but the knowledge of the Dune Guardians."

Curiously, you look at each other. "The Dune Guardians were the silent protectors of the island. They knew every beach, every sandbank, and every dangerous current. Their greatest treasure was a sea map that marked safe passages through the Wadden Sea. With it, sailors could find the right course even in thick fog." He pulls out an old leather scroll. "Just before a severe storm tide swept over the island, the guardians hid their clues in special places on Spiekeroog. No one knows today where the legacy is located. Only those who solve all the puzzles will find the final clue." With a crack, Folkert opens the leather scroll. A yellowed map of the island comes into view. Several locations are marked with a mysterious symbol. "Each of these places holds a part of the secret. Some clues are clearly visible, while others are cleverly concealed. You must observe closely, combine information, and sometimes think outside the box."

The captain smiles. "Never forget: the dunes are constantly changing. Yet true secrets never disappear – they only wait for the right ones."
With these words, your journey begins. It leads you through the historical village of the island with its old captain's houses, past the island church, up to the observation dunes, to the Utkieker, and finally out to the endless beach. Along the way, tricky puzzles, mysterious symbols, ancient inscriptions, and hidden messages await you. Each solved task brings you one step closer to the legacy of the Dune Guardians.

But be careful! Not every clue leads to the goal. Some hints have been deliberately placed to mislead treasure seekers. Only those who observe attentively, combine logically, and work together as a team will fully decipher the riddle. When you hold the last clue in your hands, you recognize the truth:
The greatest treasure of the Dune Guardians was never a chest full of gold. It was the knowledge of the island, the respect for nature, and the unity of the people who have withstood wind, weather, and sea here for centuries. Now it is up to you to preserve the legacy. Are you ready to uncover the secret of the Dune Guardians of Spiekeroog?
