In your opinion, which hero has the most charisma in the campaign?

No, Ialayu wasn't recognized because she was hiding behind rocks. She is a master of espionage, which is proven by her first mission. Railag simply sensed someone's presence. And he is loyal to Malasse and Malsare. When Ilaya told him that Malsare needed his help, he immediately began to fulfill the request. Malsara herself called him a loyal servant, and she can read minds. Her ability is mentioned in her prophecy. During their first meeting, she told Railag that one day he would be very scared and afraid of what he loves. And the aggression in his greeting is explained by the fact that he was sitting in a portal, protecting Isabel from all sorts of demons. He initially thought it was a spy.
