Rialla

During Nasuada's captivity, Galbatorix used an illusion of a woman named Rialla to try to turn Nasuada to the Imperial cause. Rialla appeared as a fellow prisoner: though Nasuada always suspected that Galbatorix was influencing Rialla, she eventually realised that she was wholly illusory due to her unusual behaviour and gaps in her memory. Rialla was removed from the cell after Nasuada denounced her.
