When you first enter Barton Town, there are going to be several red question marks all over the place. There are a lot of quests for you to pick up in Barton Town that you will be able to complete as you progress in the game. There are also several quests for you to complete within Barton Town itself. They may not pay off as big in orbs and gold as you may like, but it's still good to get all of the quests completed before progressing further.
