Basil was good at multitasking. While he had been digesting the information his mother had given him, he had also been scanning the entire forbidden section to look for the legacy of the unknown Mage of Braxtein Kingdom.
He had soon found that the legacy he was looking for wasn't there, so he immediately asked Iliana to go with him. He still didn't know where the legacy was, but he was sure he would eventually find it if he searched it outside.
Iliana, on the other hand, followed Basil willingly, but she was still curious of what Basil was actually searching for. Not only had Basil not tell her anything yet, but she also didn't know there was something worth looking for in Arthan Library.
She had honestly thought that Basil's aim had been the information of his parents since the beginning, but now that he had stated he was looking for something different, she didn't have any idea of what he was searching for.
