The Secret Elixir (Das geheime Elixier)

An old legend says that deep in the woods of Wolfenbüttel there is a secret elixir that that contains the power over natural forces.
Curt Mast, a passionate hunter and the creator of the elixir, kept its whereabouts well protected, even after his death.
An ancient document describes how every 56 years and for only a few hours between sunrise and sunset, a mysterious stag will appear in a clearing in the woods to show you the way to the elixir’s secret hiding place.

You’ve followed the stag deep into the woods and soon the outlines of an old hunting lodge between the trees will appear. Can you find the secret elixir and complete the adventure before this unique opportunity is over?
