Monica 'Moon' Lake is Jim's older sister, a sister that ran away just after she turned 17 (a few months before his 11th birthday so they are 6 years apart in age). But little did he know she left to protect not only him but their mother as well. All because there's another amulet, one meant to help not only protect troll kind but the Daylight trollhunter as well. When Jim discovers the Daylight amulet inside the remains of Kanjigar little does he know he'll regain the missing piece to his family. (Monica will be about 20/21 years old in the beginning of the story)
