ArenaNet Continuity and Lore Designer Jeff Grubb dropped a blog post discussing the three types of stories gamers will find in Guild Wars 2.
Starting with the global story:
The biggest story is the “Story of the World,” which is portrayed on the largest canvas. This is the tale of awakening of the Elder Dragons, and the threat that they pose to Tyria.
The personal story:
The biography choices you make when you create your character set you off down an initial path, but the decisions you make as you play will send you down different narrative pathways. Your story path will take you from the gates of your home city all the way to Orr and Zhaitan. Over the course of this story, your character grows in level, power, and wisdom. They realize the nature of the true enemy and rise above the more local concerns that troubled them during the early levels of the game.
Finally the sage of iconics:
The third type of story supports both the world and the personal stories: the story of the iconic characters of Guild Wars 2—Zojja, Logan, Rytlock, Caithe, and Eir. These are great heroes among their people who serve as mentors to characters of the same race. Your mentor plays an important role in your character’s life early in the game. You meet them in your first personal story adventure, and your actions impress them. Your relationship with them evolves over time as you eventually become an equal, a friend, and an ally.
All three types of story are design to build “the central theme of the game: pulling people together to face more difficult challenges.”
