Galbatorix

Galbatorix was the king of Alagaësia by force. He was chosen by a dragon and became a Rider in his early years. His dragon Jarnunvösk was killed by Urgals some years later. Galbatorix, mad with grief and hatred, asked the Dragon Rider council to grant him another dragon, but they refused, sensing his mental instability. With his request denied, Galbatorix took it upon himself to steal another dragon egg. He convinced a Dragon Rider named Morzan to leave the gates open to the place where the eggs were stored. Galbatorix stole a dragon. Then, he forced this dragon, Shruikan, to serve him by dark magic. He formed the Forsworn, a group of thirteen dragon riders and their dragons loyal only to him, and killed all the other dragons and riders in existence, or so he thought. He proceeded to create an Empire through which he ruled most of Alagaësia. He is the main antagonist of the series.
