The major seclusions seen thus far are the areas around the old-world cities of Nokia and Tampere, Finland. The Paddlewheeler crossed through this area on the Keuruu-Pori . During the travel, the ship's lights were switched off and the window shields were closed. On board, crew and passengers were instructed not to speak or make any noise, for fear of attracting beasts. Fortunately, the passenger vessel includes safeguards against potential noise.
It can also be assumed that the Mora-Öresundsbro route the Dalahästen passes through is also a seclusion, as there are many ancient ruins seen along the route as well as nesting trolls and giants (not by the passengers, of course). The sealed nature of the train car - having no lights or windows - is meant to keep what is inside the train away from what is outside. Still, it is not a perfect system, and traveling through a seclusion has certain hazards.
