She'll go through the standard opening lecture that's been repeated some uncounted number of times, while you pay attention in helpless fascination and remember the tiny little fragment of information that She deigns to warn you about in advance.
This is not where you thought you were going; this is the university that teaches mind control. Some other universities pretend to teach it too, but ignore all those, they might as well not exist.
There are classes here on every form of mind control that exists. Magical, psychic, hypnotic, neurosurgery and neurochemistry, nanotechnology, sheer persuasion.
These are your fellow students. More than half of you will leave the year enslaved to others of your number.
The system is not fair. Some of your fellow students are already more powerful than you.
It is not so much unfairness that you cannot rise above it. It is a very common outcome for the least powerful of new entrants to leave with some of the most advantaged students as their helplessly adoring slaves, if their will and wit is the greater.
Your rooms have been assigned to you already. There are classes where you pair with roommates of your own choice; this is not one of those. You will be rooming in triples, in dorm rooms that have every luxury you can imagine and some you can't.
The University teaches subtlety. When you enslave a fellow student, you must bring them to Mesmerra's office to report your success. If anyone else detects you and reports you before then -- such as one of your victim's allies, or your own enemy -- your enslavement of them is undone, and you will receive a penalty.
People may not be mentally assaulted in class, nor in the dining hall, nor the library; anywhere else is fair game.
For the first week, no student may be enslaved by any tools more mystical or material than simple hypnosis without computer aids; unless, of course, they have been persuaded to permit the use of more powerful arts upon themselves, by some contract or verbal assent.
Study well and quickly how to defend yourselves, or make pacts with those who can, or simply find a kindly-seeming owner to whom to give your despairing self; for this first week of shielding will not last long.
