Just to add to this, there is always a quest to send you to the next zone when you get mostly done with the zone you are in. However it is easy to over look these quests or sometimes even miss being given it. For example, there is a wedding in the game that if you don't talk to someone after, you don't know where in the next zone your supposed to go. I think they fixed this with a patch, but it was easy to miss close to release.
Also, you know about the quest colors? Those in Red are above your level, those in White are below your level, and those in Green are near your level.
A little TIP, you really should explore as much the map as you can, take your time and do ALL the quest.
- First, it would be sad to miss out the wonderfull stories
- Second, if you do not do all quest, you start to be under level, and you will have to grind once your reach max level to gain Champion points.
- You also often get a skill point to complete a chain quest
So better to do all the quest possible, even if they are too low for you!
