Inheritance

     Inheritance is the fourth and final book of the Inheritance Cycle. It begins in the Varden's siege of Belatona.  During the battle, Saphira is almost killed by a Dauthdaert, or Death Spear, called Niernen, which was created to kill dragons. When Belatona falls, the werecats form an alliance with the Varden. Roran is sent to siege Aroughs, and despite heavy casualties, they are successful.
     They continue on to capture Dras-Leona, where Murtagh and Thorn await them. After Jeod finds an old sewer system, Eragon, Arya, Angela, Solembum the werecat, and an elf named Wyrden, head into the city to open the gate. They are captured, and Eragon is almost killed. After entering and defeating Murtagh and Thorn, Nasuada is kidnapped by the duo. With their leader gone, Eragon is appointed as temporary leader of the Varden.
     He travels to the Rock of Kuthian, where he discovers Eldunari and dragon eggs. With their help, Eragon heads to Urubaen to face off against Galbatorix. While in captivity, Nasuada is constantly visited by Murtagh, who helps lessen her pain. They begin to fall in love with each other, and Murtagh plans to help Nasuada to escape from Galbatorix. When the siege begins, Eragon, Arya, Saphira, Elva, the Eldunari, and their elven guards travel to the throne room. In the end, all of Eragon's guards are transported into a dungeon. The remaining warriors enter the throne room. Galbatorix quickly overpowers them, and orders Murtagh and Eragon to duel. After Eragon wins, he taunts Galbatorix into a duel.
     When Galbatorix's wards are stripped off by Murtagh, Galbatorix knocks him out and attacks Eragon mentally. Eragon manages to cast a spell that makes Galbatorix feel everything that people who were affected by him felt. While he is suffering, Arya kills his dragon Shruikan. Galbatorix says a spell to un-make himself. As the citadel falls, Arya rescues the dragon egg and the other elves.
     Murtagh decides that he and Thorn will travel around the world, for Nasuada, as well as himself. Nasuada is  chosen as the Queen of Alagaesia. Arya becomes the Queen of the elves, and a dragon rider. Eragon decides that for the safety of everyone, he and the dragons will move to another land. Eragon and Arya decide to re-meet one day.
