Secret Files
Various thoughts flashed through Michael's mind when he realized that Alice knew his sister. He had been convinced that he didn't care about his family anymore. Only his brother had been of importance to Michael. Despite that, something in the back of his mind kept nagging at him, telling him to research more about his sister, and find out more information about her.
Doubts popped up in his mind, and he began to wonder what must have happened for Hesta, the 'War Empress', to disappear the day she advanced to the 4th Tier. While his mind went down the rabbit hole, Michael didn't even realize when he opened his parents' chat.
He listened to the messages they'd sent, only to end up frowning deeply. The audio files they sent through starnet messenger were deleted shortly after Michael listened to it, but Michael didn't pay much attention to that. He could only frown, staring blankly at the now-empty chat between him and his parents.
