weaves together three story types ，Guild Wars 2

ArenaNet Continuity and Lore Designer Jeff Grubb claims that there are three types of stories that players will encounter in Guild Wars 2, and he's written up an informative post explaining how the team has woven these tales into the game. "This is an underlying theme of the game -- people coming together and cooperating to fight a greater foe," Grubb explains.
 

The first type is what he calls Story of the World. This is the over-arching narrative that deals with the biggest threat to the world (the Elder Dragons) and how it is to be countered. （Guild Wars 2）ArenaNet chose to use dynamic events to tell these stories so that players are gradually made aware of the threat.

The second story type is your personal one, which tells of your own rise to power, fame, and glory in a variety of ways. Finally, there's the story of the five central iconic characters in the game (Destiny's Edge) and how they relate to you and each other.
