The Inheritance Cycle is set in the fictional world of Alagaësia, the novels focus on a teenage boy named Eragon and his dragon Saphira.
In the fictional land of Alagaesia, there was an order who oversaw the countries and brought peace to the world. This group was known as the Shur'tugal or Dragon Riders, for they rode Dragons, which they were bonded with at the birth of their dragon, in accordance with a pact made between elves and dragon millennia earlier. One Dragon Rider named Galbatorix had his dragon slain by a group of Urgals (somewhat similar to Orcs from other fantasy) which drove him mad. Denied another Dragon by the Council of Elder Riders, Galbatorix blamed the Council for the death of his dragon and sought to destroy the order. He made an alliance with a young rider, named Morzan, and with his help slew an elder rider. Then, with the help of Morzan, the first of the thirteen Forsworn, he stole a black dragon, named Shruikan. He forced Shruikan to bind with him, and later destroyed the Riders and their dragons, except the thirteen Forsworn. Since then, he ruled parts of Alagaesia as a tyrannical King. He never ruled both the elves nor dwarves.
