Editing Eldest (section)

=== Plot ===
''Eldest'' begins as [[Ajihad]], the leader of the rebel Varden force, is ambushed and killed, while The Twins and [[Characters in the Inheritance Cycle#Murtagh|Murtagh]] are assumed dead. Ajihad's daughter [[Nasuada]] is elected to command the Varden, and decides to move them to Surda and oppose the Empire openly. Eragon and Saphira decide to travel to the forest [[Du Weldenvarden]] to be trained as a [[Dragon Rider (Inheritance Cycle)|Dragon Rider]] by the elves. The dwarf king, [[Hrothgar (Inheritance)|Hrothgar]], adopts Eragon to his clan and has his now foster brother, Orik, accompany him to the forest. There, Eragon meets the stranger who had contacted him, revealed to be a Rider, [[Oromis]], with his Dragon [[Glaedr]], the only Dragon and Rider secretly alive. However, both are crippled, and so cannot fight [[Galbatorix]] directly, choosing to pass on their knowledge. Eragon and Saphira are taught the use of logic, magic theory, scholarship, and combat, among other things.

However, having received a back injury in the previous book, Eragon is beset by agonizing seizures, which debilitate him. He also struggles with his romantic feelings for Arya, while Saphira has similar struggles toward Glaedr. Arya becomes aware of his feelings, and distances herself from him, while Saphira is violently rejected by Glaedr, though the two come to an understanding afterwards. Eventually, in an ancient elven ceremony, the Agaetí Blödhren, Eragon is affected by powerful magic, turning him into an elf-human hybrid, and healing his back injury. He makes another romantic attempt on Arya, but she gently rejects him, and leaves to rejoin the Varden.

Meanwhile, unknowing of all of this, Eragon's cousin Roran, returning home after hearing of his father's death, plans to marry Katrina, daughter of Sloan, the village butcher, while the village is unexpectedly attacked by Galbatorix's soldiers and the Ra'zac, who had killed Garrow. Roran fights the soldiers with a hammer, which becomes his signature weapon while the entire village mounts a defence, during which Roran proposes to Katrina, but ignites a feud between himself and Sloan in the process. One night, Roran wakes up to find Katrina being taken by the Ra'zac, who sneaked into the house. They seriously injure him and capture Katrina. Sloan, revealed to be in league with the Ra'zac, is then knocked out and flown away by them, along with Katrina, on their mounts and parents, the Lethrblaka.

Torn between chasing after Katrina and staying behind to defend his home, Roran rallies almost the entirety of the village to travel to Surda and join the Varden. On the way, they journey to Teirm, where Roran meets Jeod, Brom's friend, who informs him about Eragon, and decides to go with them. With Jeod's help, they steal a ship, and journey toward Surda by sea.

Meanwhile, Nasuada struggles under the burdens of leadership. She hatches a plan to fund them by selling magically-crafted lace, to alleviate their financial troubles. She also meets Elva, a child supposedly blessed by Eragon in the previous book. Eragon is revealed to have botched the blessing with poor phrasing, accidentally forcing Elva to feel the pain of others. Elva uses her abilities to save Nasuada from an assassination attempt. Nasuada eventually learns that Galbatorix is fielding a massive army against them, and sends for help from the dwarves and Eragon.

Eragon has a prophetic dream of the coming battle, and decides to interrupt his training to aid the Varden in battle. Oromis consents and provides him with numerous gifts to help him, but insists he return to finish his training after the battle. He journeys with Saphira and Orik to the Varden's camp, reuniting with Nasuada and Arya, and meeting Elva, promising to rid her of his failed blessing and reconciling with Arya. The Varden are then joined by an army of Urgals, led by Nar Garzhvog, who seek an alliance with them after being freed of Durza's control.

As the battle begins, it goes poorly for the massively outnumbered Varden. Roran and the dwarves arrive mid-battle, and begin to turn the tide in favor of the Varden, but an unknown Dragon Rider unexpectedly arrives and kills Hrothgar. Eragon engages this Rider, who proves an even match, and unmasks him, revealing him to be Murtagh. Murtagh reveals he was kidnapped by the Twins, who had betrayed the Varden. After the dragon, named Thorn, had hatched for him, they were both forced into swearing loyalty by Galbatorix in the ancient language, binding them to his will. Meanwhile, the battle proceeds, with the Twins revealing themselves and causing massive losses among the Varden, until Roran kills them.

Murtagh and Eragon resume their fight, with Murtagh easily defeating Eragon through magic. He shows mercy to him, on account of their old friendship, but takes Eragon's sword Zar'roc, which he claims to be his inheritance, revealing that he and Eragon are brothers, making Eragon a son of Morzan, the first of the traitorous Riders known as the Forsworn who was later killed by Brom.

Ultimately, the Varden win the battle. The book ends as Roran asks Eragon for help in rescuing Katrina, to which he agrees.
