Eragon uses all the energy in Aren to blast a large boulder at Thorn, saving the Varden. Later, Murtagh attacks again and captures Nasuada. Then, Eragon remembers about the Rock of Kuthian and questions Solembum. Solembum shows him a page in the Domia abr Wyrda which says that the Rock of Kuthian is on Vroengard, the ancestral home of the Riders. Eragon soon learns that someone hascast a spell that makes everyone but him, Saphira and the werecats forget about the Rock and somehow forces Glaedr to come with him. They fly toward Vroengard with high hopes of fulfilling the prophecy. Meanwhile, Nasuada is being tortured by Galbatorix to become his willing servant. Strangely, Murtagh shows affection toward her. When Eragon reaches Vroengard, he and Saphira realize that they must speak their true names. Soon, inspired by the sunrise, Eragon realizes his true name as does Saphira. Saphira, Eragon and Glaedr share their true names and then open the Vault of Souls. Inside, they find a treasure trove of Eldunari and dragon eggs. Upon the instruction of Vrael's dragon, Umaroth, they cast a spell to bring te Eldunari with them. Upon leaving, another spell forces them to forget about the eggs. The Varden defeat Dras-Leona and march toward Uru'baen. Eragon breaks into Glabatorix's castle with the help of the 12 spellcasters, Arya, and Elva, who agrees to help. The 12 spellcasters are taken away and Arya, Eragon, Elva and Saphira are captured by Galbatorix. He talks to them and tells them that he has found the true name of the ancient language. Then, when Eragon challenges him to a duel, upon Umaroth's urging, he makes Eragon fight Murtagh. Eragon grieviously wounds Murtagh in the course of the fighting and Murtagh uses the true name of the ancient language to remove Galbatorix's wards. Thorn attacks Shruikan and Arya kills Shruikan with an ancient weapon called the Dauthdaert. At the same time, using the power of the Eldunari, Eragon makes Galbatorix understand all the pain he has inflicted upon others. While Galbatorix is reeling, Eragon stabs him in the stomach. Galbatorix, in desperation, tries to kill Eragon in a suicide move. In the ancient language, he screams "Be not!" and turns himself into antimatter. Eragon puts wards around everyone with all the Eldunari's help and Galbatorix died. During this time, a man named Barst had killed Queen Islanzadi and so new leaders had to be elected. Nasuada becomes queen of the Empire and Orrin gains control of a few provinces. Lastly, Arya takes control of the elves. Eragon receives a letter from Arya to meet in secret and that day, he realizes that Arya has a dragon named Firnen. Saphira loves Firnen but Eragon realizes he has to leave Alagaesia in order to train the new Riders. No place in Alagaesia would be fit to raise dragons. And; as according to the prophecy, he leaves Alagaesia forever, never to see Arya, Nasuada, Roran or Katrina again.
