Guild Wars 2 players will be happy to hear that ArenaNet will be adding elements of the Living Story to fractals. According to forum posts by Colin Johanson, fractals are "perfect places for this kind of 'historical' experience.
In the future, you’ll see certain types of content that was part of larger story experiences be updated to work within the fractals dungeon and return there where it makes sense to do so. Of course, the specific rewards and achievements will not return since those are intended to be completed as the story unfolds, but the content itself will be used to expand out our fractals experience and serve as a place to continue to experience great (and strange) moments in history.
