"So it's for my sake? For Atreia's? Do not insult my intelligence!" Caelid remained opposed to Phernos's plan, but was unable to provide an alternative. You dissolved the mysterious barrier with Meslamtaeda's blood and finally met Reda, the High Priestess of Illusion. Everything you had learned while tracking her turned out to be true. Reda lost her daughter, Teina, while guarding the Core, and turned to dark magic in an attempt to bring her back, slowly going mad in the process. She came to resent Phernos for burdening her with her lonely duty. Reda refused to reveal the location of the Core, and demanded that you return Teina's bracelet to her. You decided to help her first before resuming your search for the Core.
