In the world of Eragon, Durza is not the only shade in existence. Shades are sorcerers who have allowed dark magic to corrupt them, turning them into powerful and malevolent beings. While Durza is a significant shade in the story, there are others mentioned throughout the series.
The main ones are the Ra-zac, the Shade Durza, and Galbatorix.
