Starting area
You may encounter Skie here if she has joined the expedition ("Skie's Grand Plan" side quest). No matter how you'll react she'll be sent back to camp.
If you want to leave this map go to one of its edges.
Campsite
Ikros and Isabella can be found here and you can help them in getting rid of a vampire Tsolak - "Isabella and Ikros" side quest. Alternatively you can provoke them to attack you or you can side with the vampire when he shows up in the camp.
Isabella is carrying a shield belonging to Takos (M7,3) - you can receive it as a reward for completing the quest or you can take it by force.
Attacked cart
There's a large group of orcs and wargs near the cart. Once they're dead you can search the cart for treasures.
Cave
There are four traps outside of the cave and you can use a thief to disarm them.
Inside the cave you'll find a coffin belonging to the vampire Tsolak. If the creature is inside the coffin then you may use a wooden stake to kill it ("Isabella and Ikros" side quest).
Southern road
You may encounter a monk named Rasaad here and he'll agree to join your group.
Basic information about Coast Way Forest
The above map shows a small Coast Way Forest, which adjoins the Coast Way Crossing (M7 map). The forest can be reached from the world map, and the location isn't obligatory, as this place doesn't have any tasks connected to the main quest. Nevertheless, the journey to this place is recommended, as you can finish one bigger side-quest, and recruit Rasaad, a monk, to the party.
The most important spots in Coast Way Forest
2. Encampment
Here you can meet Ikros and Isabella, who are hunting for the vampire Tsolak, which is the basis of the side-quest Isabella and Ikros. You can help them get rid of the monster, or provoke them to a fight, or take the vampire's side after he shows up in the camp.
Valuable information - Isabella has a shield which is sought by Takos (M7,3) - Halfling Treasures side-quest. The item can be received as a reward for killing the vampire, or be taken from the Isabella's corpse, if you decide to attack the duo.
5. Southern road
Rasaad can be met near the southern road. He can be invited to the party, or sent to the Flaming Fist encampment.
