Having viewed the memories of Misty's entire life, Tyler was able to gain a lot of useful pieces of information such as a detailed structure of the Alcar family's operation system. That is to say, he now understood what the inner workings of one of the Great Five noble families were like.
He had also learned the faces of all the higher-ranked officers Misty had interacted with, and for someone who had been considered a lower life form, she had met most of the high-ranking nobles. Including members of the so-called pillars of the family.
While most of the more sensitive information had been sealed behind a seemingly unbreakable barrier, Tyler didn't think he would have much trouble forcing them out. However, doing such a thing would cause a backlash that would most likely kill Misty and send information about him back to the one who had placed those restrictions on her mind.
