Q:
How do the books relate chronologically?
A:
The books chronologically occur before Guild Wars 2. I think they were also released before the game so fans could gain an understanding of the Guild Wars 2 world before actually seeing it in game.
Perfect, thank you!
Sea of Sorrows happens a good amount before GW2, the other two novels are set a few years before the game starts. Sea of Sorrows falls very roughly halfway between GW1 and GW2. As such, Sea of Sorrows events are already pretty old history by the time the game starts.
To be very specific:
Ghosts of Ascalon was the first one published, 25 months before GW2 launched. It’s set in 1324 A.E., one year before GW2 starts.
Edge of Destiny was published 20 months before the game launched. It’s set in 1319-20, six-five years before the events of the game.
Sea of Sorrows was published ten months after the game launched, in the middle of Season 1 of the Living World. It’s divided into four acts strung between 1219 and 1256, 106-69 years before the game starts.
