The Rithmatist

seats. Schematics depicting Rithmatic defenses hung on the whitewashed walls, and the plush seats were bolted in rows along the tiers, facing toward the lecture floor below.
    A few of the students glanced at Joel as he entered, but Professor Fitch did not. The professor rarely noticed when he got deliveries from the office, and would ramble on for the entire lecture before realizing that a member of his audience wasn’t actually a member of the class. Joel didn’t mind that one bit. He sat down on the steps eagerly. Today’s lecture, it appeared, was on the Easton Defense.
    “… is why this defense is one of the very best to use against an aggressive assault from multiple sides,” Fitch was saying down below. He pointed with a long red baton toward the floor where he’d drawn a large circle. The hall was arranged so that the students could look down at his Rithmatic drawings on the ground.
    With his pointer, Fitch gestured toward the Lines of Forbiddance he’d affixed to the bind points on the circle. “Now, the Easton Defense is most famous for the large number of smaller circles drawn at the bind points. Drawing nine other circles like this can be time-consuming, but they will prove well worth the time in defensive capabilities.
    “You can see that the inner lines form an irregular nonagon, and the number of arms you leave off will determine how much room you have to draw, but also how stable your figure is. Of course, if you want a more aggressive defense, you can also use the bind points for chalklings.”
    What about Lines of Vigor? Joel thought. How do you defend against those?
    Joel didn’t ask; he dared not draw attention to himself. That might make Fitch ask for his message, and that would leave Joel with no reason to keep listening. So, Joel just listened. The office wouldn’t expect him back for some time.
    He leaned forward, willing one of the other students to ask about the Lines of Vigor. They didn’t. The young Rithmatists lounged in their seats, boys in white slacks, girls in white skirts, both in grey sweaters—colors to disguise the ever-present chalk dust.
    Professor Fitch himself wore a deep red coat. Thick, with straight, starched cuffs, the coat reached all the way down to Fitch’s feet. The coat buttoned up to a tall collar, mostly obscuring the white suit Fitch wore beneath. It had a militaristic feel to it, with all of those stiff lines and straps at the shoulders almost like rank insignia. The red coat was the symbol of a full Rithmatic professor.
    “And that is why a Keblin Defense is inferior to the Easton in most situations.” Professor Fitch smiled, turning to regard the class. He was an older man, greying at the temples, with a spindly figure. The coat gave him an air of dignity.
    Do you understand what you have? Joel thought, looking over the unengaged students. This was a class of fifteen- and sixteen-year-old students, making them Joel’s age. Despite their noble calling, they acted like … well, teenagers.
    Fitch was known to run a loose classroom, and many of the students took advantage, ignoring the lecture, whispering with friends or lounging and staring at the ceiling. Several near Joel actually appeared to be sleeping. He didn’t know their names—he didn’t know the names of most of the Rithmatic students. They generally rebuffed his attempts to chat with them.
    When nobody spoke, Fitch knelt and pressed his chalk against the drawing he’d done. He closed his eyes. Seconds later, the drawing puffed away, willed by its creator to vanish.
    “Well, then,” he said, raising his chalk. “If there are no questions, perhaps we can discuss how to beat an Easton Defense. The more astute of you will have noticed that I made no mention of Lines of Vigor. That is because those are better talked about from an offensive viewpoint. If we were to—”
    The door to the lecture hall banged open. Fitch rose, chalk held between two fingers, eyebrows raised as he turned.
    A tall figure strode into the room, causing some of the lounging students to perk up. The newcomer wore a grey coat after the style of a Rithmatic professor of low rank. The man was young, with stark blond hair and a firm step. His coat fit him well, buttoned up to the chin, loose through the legs. Joel didn’t know him.
    “Yes?” Professor Fitch asked.
    The newcomer walked all the way to the floor of the lecture hall, passing Professor Fitch and pulling out a piece of red chalk. The newcomer turned,
