Oh! an important thing.
Chapter 2 will be completed after you reach to the Tower of Lust in Amirian island, which should be marked in your quest logs too, under Amirian Curse - The haunted island and Chapter 2's last quest stage: Sail to Amirian Island.
You need to go to Dawn Harbour and hire a boat to the island, the price may look a bit expensive at first, but it was done to pull the player to explore and earn some coins on battles and the capital city events.
The Westbrook passage to the north will be unlocked on chapter 3, as you come back from the cursed island.
Many chapters will require to conclude moving to the island and unlock different dungeons.
I hope it helps 😃
