The Harbor (part 1)
After you leave the Sewers you will start your second mission "Go past the Harbor".
The First Campfire
The Tree and Items
In the first zone of the Harbor, you can find a lot of items scattered in the ground (for example, Arrows for the Crossbow Weapons).
Also, there is a tree in the top of the hill where is a zone to take a first peek of the full Harbor zone (useful to start making a possible route to evade enemies).
