Dragon Fantasy: Volumes of Westeria

Story-related and cannot be missed.

In Chapter 1, in Bluefin, in the big pirate hall (top center of the map) talk to the pirate in front of the door. He’ll send you on a quest to talk to a few people, first the pirate in the other room (bar), then to someone in the inn, back to the pirate at the bar, then to the shopkeeper in the lower right of the group of shops, and finally back to the pirate in front of the door. The door will be opened finally. Go in and talk to the Pirate Captain, he will ask you to pick up a soda from where he left it to the east of Wester.

There will be an obvious craggy mountain in the middle of passable ones. Walk on the square south of the mountain and you will pick up the soda. The trophy will pop here, but to finish the quest you will have to take the ship back (Warping makes the soda flat) and on your way, you will fight a Kraken. The Kraken will give up a key when it dies. Talk to the Captain when you return and you will find that the key will open up the next place to go in the story.
