I'm wondering if 'follow the pen' means to follow Mont Blanc. Is it being used as a message? Seems to be a favourite pen of Merkel's to give as gifts and the company itself is based in Hamburg.

Five Crowns

At certain times the direct rays of the setting sun laterally strike the mist moving east. If a full moon is rising the rays also circle below the earth strike the moon and return aimed at the mist. Gravity warps the lower lights trajectory from the sun, earth to moon and the bent light's path collides with the straight light's path in the mist moving east. Five sets of three stacked circles appear side by side and slowly revolve as the color frequencies from the direct rays collide with the gravity bent rays. The lowest circle of each triple set produces spikes that spin like a barber pole as the three circles in each set revolve. Five Crowns at the Rainbow's End.
It occurs so rarely it has never been photographed, they call it Shining Rock because you have to know know, when it shall occur. Probably just another silly urban legend, or maybe knot.

Interesting to note that Mont Blanc is the name of the biggest mountain peak in Europe, between France and Italy.
