At the end of Inheritance, Eragon decides to leave Alagaësia. He chooses to journey to what is known as the home of the Dragons, a place where he hopes to explore and build a new future for himself and the dragons. This decision is heavily influenced by the events that transpired throughout the series, particularly his responsibilities as a Dragon Rider and the loss of those dear to him.
Eragon realizes that the world of Alagaësia will continue to change and shift without him as he leaves behind the burdens of leadership and conflict. His journey symbolizes not just a physical departure but also a deep emotional choice to embrace new beginnings and the unknown. He takes with him the last of the dragon eggs to help repopulate the dragon race and ensure that they thrive once more.
