This is set in aldersprig's Doomsday Academy, several years after its founding. Leofric is my character who exists canonically in the setting because I am a lucky bastard.
Also I tried to match Lyn's First Day series and wound up almost twice as long and hating it but them's the breaks.
Leofric was sitting at his desk as the new students trickled into the classroom, pretending not to pay attention as they picked out their seats. Even after they'd all sat down, he continued letting the students chatter quietly to each other as he covertly took in the dynamics. It hadn't been a problem yet, but he liked to watch for anyone being left out.
This year looked good again, he noted, mentally chalking up another point for Ascha's handling of the youngest students. As the first bell chimed, he finally stood and looked out over the students.
“Good morning!” Leofric smiled cheerfully as they all looked up. “I am, as you probably know, Professor Inazuma, your mathematics teacher for the next few years.” He picked up a piece of chalk, tossing it into the air as he spoke. “We'll be covering a lot of different material this year, but first...” He caught the piece of chalk, then turned and drew a circle and a triangle on the board behind him. “Geometry! Do any of you know what geometry is?”
He looked over the students. None of the students seemed about to answer; one, though, a dark-haired boy with darker skin, looked a little nervous. The other six kept sneaking expectant glances at him.
“Geometry,” Leofric continued, “is the mathematics of shapes.” The glances were getting more pointed and one girl nudged the nervous kid with her foot, but Leofric continued pretending not to notice. “And these two,” he tapped the chalk against the board, “are the shapes we'll be working with for the next few weeks.”
“Um...” The nervous boy finally spoke. “Professor Inazuma?”
“Yes?” Leofric paused, smiling encouragingly at the kid.
“We, um, were wondering...” He glanced around at the other students. “Did you really get that scar in a battle with the Nameless?”
Everyone looked up at Leofric, waiting for the answer. The corner of his mouth twitched in barely-repressed amusement. “Well, I have fought them before.” Their eyes widened and the foot-nudging girl leaned forward eagerly. “But that's a story for another time.” He tapped the chalk loudly against the board as the students protested. “Pay attention and maybe we'll have time after class.”
