Guild Wars 2 takes place in the high fantasy world of Tyria, 250 years after the defeat of the Great Destroyer in the Eye of the North expansion. During the time between that event and the start of Guild Wars 2, five so-called Elder Dragons sleeping beneath the continent have awoken, causing widespread destruction to Tyria and corrupting its inhabitants. The role of the player is to reunite the disbanded Destiny's Edge, a multi-racial adventuring guild, whose combined strength is needed to effectively combat Zhaitan, the undead Elder Dragon.
