A new developer diary has been posted to the official Guild Wars 2 site. This time, Leif Chappelle does the honors and goes into specific detail about how the Living World Team goes about crafting the "living, breathing world".
The story of the world needs time to gain momentum, and so the Living World team started gradually while we took the time to develop out the large years-spanning plot and characters that we’re now prepared to unleash into Tyria.
What we’re creating is an actual chronology of the world. Flame and Frost has taken several months to develop, but it’s just one story arc within the overall plot beginning to unfold. The events of Flame and Frost will create repercussions throughout the world, bringing new tales and conflicts to light. Through the course of 2013, the concept of these Living World releases will grow in scope and grandeur as we move ahead and build up the groundwork to make this a key component of the developing and ever-changing world of Guild Wars 2.
