Guild Wars: Eye of the North is the first true expansion for the Guild Wars franchise, providing new content geared exclusively for level 20 characters*.

Return to the battle-scarred continent of Tyria, home of the original Guild Wars campaign. There, old friends await, ready to help you settle past scores. But an even greater threat looms... The land has erupted, spewing forth a race of beings with only one thought—destroy everything. Win or lose, your actions will set the stage for Guild Wars 2.

*Eye of the North content has been designed with level 20 characters in mind, however as of December 6th, 2007 characters from level 10 can now also enter and will automatically receive a buff called Journey to the North while in Eye of the North locations to enable them to be treated like level 20 characters.
