Eldest is the second book in the Inheritance series, coming after the book Eragon. It begins after the shade Durza has been killed by the Rider Eragon with the help of Arya, the elf, and Saphira, the dragon. Over the course of the book Nasuada, the daughter of the leader of the Varden, must take up leadership while Eragon goes to Du Weldenvarden to train with the elves. Murtagh is taken captive and seemingly killed and Saphira attacks her master while training. Eragon himself becomes part elf through the help of some dragons and is healed before the Varden fight a huge battle with the Urgal and Murtagh. Murtagh, who was taken to Galabatorix rather than killed, has been turned and is discovered to be Eragon's brother, making Eragon also Morzan's son.
