Eragon (Ed Speelers) tells Ajihad (Djimon Hounsou) that he will fight the Urgal invasion alongside the Varden. Eragon and Durza the Shade fight, and Eragon kills him by stabbing his sword Zar'roc through Durza'sd heart. The Urgals retreat. Eragon and Saphira (Rachel Weisz) follow Arya (Sienna Guillory) on her way to the elf village of Ellesmira, but she tells them to stay behind as they are now legends to the Varden and will be called upon if they are needed again. And elsewhere, Galbatorix (John Malkovich) cuts away his map of Alagaesia, revealing his dragon.
FYI, this is totally off from what happens in the book, like almost 100%.
Fans should beware.
