Come in touch with the "wilderness" of Nybæk Plantage!
At stage 1 you will find the NORTH coordinates oft the FINAL. Look for a Mikro on the branch of a fir tree.
At stage 2 you will discover an "other". Take the EAST coordinates of the FINAL with you. The other is placed on a branch of the tree. Just look at the spoiler picture if needed.
The final will be a small cache somewhere in the green wilderness.
Happy hunting!
