The pedestal with constellations has three sections with switches in the form of arrows. The switch of each section can be scrolled, setting it to the desired constellation. Next to the pedestal is a flower figure, painted in colors identical to those shown on the hint.
Each element of nature has a combination of three constellations (one constellation on each petal of the flower), and the task of the players is to set the switches to the constellations of each element in turn: water-earth-fire-air. As each combination is selected, the corresponding constellations will light up on the pedestal.
If constellations are correctly placed on each element of nature, a cache will open.
