Nieblarz

As the leaves of the Nieblev are sought after both for cuisine and for potionmaking, the Nieblarz (old talian dialect for Nieblev farmer) is a profession in demand. Harvesting and in most cases drying the blue leaves is most of the time not a dangerous occupation, but it requires a healthy body and a good lung, as the nieblarz dive to the treetops near the coast, without any gear. 
They take a fisher boat or a comparable vessel out on the water and farm the ever regrowing leaves until their ship is filled with their harvest. Afterwards, in the summer on ropes hung near the beach in the sun, and in winter near fireplaces, the leaves are dried till no more liquid is left in them. Now they can be transported for longer times and are sold to traders bringing them to towns all over the continent.
