Eragon, a young adult fantasy novel, is the first book in the Inheritance Cycle. It tells the story of a young boy named Eragon who hatches a dragon, Saphira, out of a mysterious stone he finds in the woods. Eragon bonds closely with Saphira and becomes a dragon rider, drawing the attention of the evil king Galbatorix, who sends his servants, the Ra'zac, to kill him. While escaping from the Ra'zac, Eragon and his mentor Brom become embroiled in plots against the evil king.
Eragon awakes to find that the Urgals are invading. The warriors quickly pour the pitch and Eragon is sickened by the sight. The number of the Urgals is disturbing all by itself and Eragon watches as the archers take aim. They reappear faster than they can be killed though. They finally break through the line of pikes and attack the warriors behind, bringing Eragon and Saphira into the battle.
Using both magic and sword, Eragon kills dozens of Urgals, working together with Saphira to keep each other safe from them. They work in tandem, Saphira surprising them and Eragon swooping into kill them. From above, Eragon notes the lack of communication between the Urgals and tells the Twins his thoughts. They send him to fight with Hrothgar where the battle is going poorly, scaring the Urgals as Saphira swoops in and setting the dwarves upon them. An Urgal manages to hit Eragon in the back of the head though and is about to kill him when Angela kills it with a double-sided sword of her own, Solembum at her side as a boy.
The Twins contact Eragon and tell him to collapse another tunnel as the Urgals continue to dig up through them to reach Tronjheim. They start to leave as an Urgal thumps Saphira in the chest with an ax. Arya manages to kill the Urgal, but Saphira is severely hurt. She continues to fight though, even after Eragon asks how she is doing.
After landing, Eragon grabs a leather pad and slides for ten minutes down the tunnel to reach where he must collapse it. The Urgals are already breaking through the tunnels and he is unsure of what to do as the Shade, Durza approaches him. He is dressed in all black armor and has a battle worn sword and a snakeskin cloak. He knows right away that he must pierce the Shade through the heart.
The two face off and Durza tries to threaten and intimidate Eragon. Eragon is unable to get help from Saphira as she is too far away, and Durza attacks, throwing his sword and attacking mentally at the same time. Eragon manages to deflect the physical attack but is knocked from his feet by the Shade’s magic. Eragon manages to strike from the ground and push back the Shade. He weakens the Shade and attacks with his mind, reaching in and seeing the Shade’s memories from childhood.
It turns out that Durza was the young boy of outcasts, named Carsaib. The Shade is in great pain and Eragon is forced back by the power of those memories. He sees Durza walk away from his parents’ graves and is charged by Durza, knocked to the ground in pain once again. A moment later, Arya and Saphira descend through the glass ceiling and distract Durza long enough for Eragon to utter his first magic word again and pierce Durza’s heart with a flaming sword plunge. He manages to kill the Shade and collapses, once again unconscious.
