Supervisor

The Supervisor is a supporting character of the Arcane Advent Series, the leader of Hollow, and a Lectormens.

Appearance
She is a small girl, roughly Aria’s size, wearing a black dress that extended to her ankles, with a gray fur stole covering the area between her shoulders and her elbows. Her black hair, which was dotted by stray strands of gray, extended down her back with a single decoration: an amber hair band, the same color as her eyes.

Personality
She is civilized and restrains the use of her overpowered abilities, but she's not above pressuring others. She refers to everyone by Mister or Miss while in the presence of others, with the exception of Luna and Ramona.

Also, she dislike profanity being used near her.

Volume II
The Supervisor reads Leidolf's mind while he's in the coma to discover what happened and prevents him from attempting to escape after he wakes up. She blackmails him into joining their organization for his safety and the child's, along with the fact she sensed something inside of him, while acknowledging that she's setting herself up as a villain. In an act of compliance for Leidolf's corporation, she agreed to a Mage's Geis to protect Aria under the penalty of a severely reduced lifespan and abilities if she breaks it, and introduces him to the rest of the staff.

The rest of the volume, she mostly interacts with Ramona Synclair and comments on their progress, eventually assigning Leidolf to his first mission along with Fai. After their return, she dives into Leidolf's mind to pull him back to reality and reverse the damage done to his mind by the grimoire. During this time, Leidolf's consciousness apologizes for his actions, and she sees what lies hidden in his mind, shedding a single tear at the sight. After he wakes up, she falls asleep in Ramona's arms.

The end of the volume has her receiving notice that Acario may be coming after Leidolf in the future.

Side Story
In the first side story, she works to prevent Leidolf's contaimenation by the grimoire by informing him of the Doppelganger and helping him solve the riddle the Huldra gave him.

Lectormens Art
The Supervisor is a Lectormens, which is an difficult form of magick, but allows for various things.

She can read someone's mind and memories at a distance, and pull someone from a coma depending on the situation. She can set up mental blocks to protect from outside interference as well.

Knowledge
She is competent enough to know the ins and outs of the world of mages, despite being only 10. This is one of the reasons she could master Lectormens Art.

Trivia

 * In contrast to Aria's bright clothing, she prefers black.

Quotes

 * (To Leidolf) "Mister Leidolf, as you should well know by now, what’s right and what’s wrong varies from person to person, especially with mages. The majority of us have very little morals when it comes to ambitions and goals."
 * (To Ramona) "‘In the end, the only one a person has to answer to is themselves.’ was something he told that child. I’ll admit that this is an underhanded tactic, but I believe it’s best for them and us."
