Hint

The faerie is an enemy and she is blocking your way.

In the French original, the compass is called "wind-rose", and the four winds recite the Latin forms of the word "rose": "Rosa, Rosae, Rosae, Rosam..."

Spoiler

Kill the faerie and go east. Take the compass and lay it on the calvary in the center of the sky.
