Facts

So what facts do we know?

• They are aliens, i.e. come from another universe (Behind Dark Bars)
• They love dark items (Dark Bird)
• They love art – not necessary Italian? (The Face of the Man in Dark)
• They love high-tech and numbers (Lottery)
• They love animals (Dark Birds, A Pet for the Man in Dark)
• They are interested in Geocachers (Bright Stars in Dark Space, Sightseeing with the Man in Dark, The Trap)
• They have their own problems (Lost in the Dark)

This was quite an interesting set of information and it enabled me to find out when their first item was displayed on our planet:

This was published already in 1502!
So since more than half a millennium "they" are around!

But what is much more important:
By looking for a dark picture, featuring an animal, an alien landscape, some artistic stuff, a human Geocacher(?) lost in his/her thoughts over a puzzle cache(?), showing some numbers and quite a bit of a mess, I found that indeed in the year 1514 such a picture was published.
Furthermore, this picture contains a secret code pointing to an object that is located in today's Brussels (placed in 2001?)!
My research revealed that with the following keys you can uncover the location of this object clearly of alien nature:

North: 50°B1A4.B1D2C2´



East: 4°A1D2.C4C2D4´

No calculations needed!
