Sebastian, burdened by painful guilt and isolation, distances himself from his past mistakes, choices and-friends as he's struggling to find some redemption. As he navigates this new path filled with dark creatures and even darker choices, he finds himself entangled with a group of wizards determined to get rid of the remnants of Rookwood's gang. But can he really prove himself this way, or is he destined to keep falling further into the shadows? ! This is a small additional part of the first story of the series, which takes place at the same time as the start of the main first story, which is right after the 5th year and before Sebastian reaches out to his friends for the first time.
