Guild Wars Eye of the North, sometimes abbreviated to EotN or GW:EN, is the fourth purchasable installment in the original Guild Wars game. It is intended to tie the Guild Wars storyline with that of Guild Wars 2. Instead of using a campaign format used by Guild Wars Factions and Guild Wars Nightfall, Eye of the North is a traditional expansion on any of the existing campaigns, rather than a standalone game. Players cannot create characters based on the expansion; there is no tutorial area or additional professions. Eye of the North was released on August 31st, 2007.
The setting for the expansion is in part subterranean and spread through the continent of Tyria, which has already been introduced by the original campaign. Players may explore the homeland of the Charr, meet the Asura and Norn, and witness the birth of the Sylvari. The Charr, Norn, Asura and Sylvari are playable races in Guild Wars 2.
The main story involves the Dwarves and introduces the Destroyers, Asura, the Norn and the Ebon Vanguard, and concludes with the battle against the Great Destroyer. Apart from the start of the journey and the ending battles, players will spend most of their time in the individual story arcs for the new Asura and Norn races as well as the Ebon Vanguard. These can be done in any order.
Eye of the North is rich in many side quests, mini missions or other activities not directly tied into the story. Foremost among these are the dungeons (some of which are visited by the main story, but most are not), which combine high end difficulty with precious rewards.
