The Secret Elixir

An old legend suggests that deep within the forests of Wolfenbüttel, a secret elixir exists, carrying the powers of nature within it. Curt Mast, once the creator of this precious item and a passionate hunter, is said to have protected it remarkably well even after his death. From an old document, you have learned that in a particular clearing, every 56 years and for only a few hours between sunrise and sunset, a mysterious deer appears that can guide your way to this place. You have followed the deer deep into the forest and soon the silhouette of an old hunting cabin emerges among the trees. Can you find the secret elixir and pass the adventure before this unique opportunity passes by?
