Hello Everyone, Reader Here! Finished my playthrough of Fire Emblem: Three Houses and I enjoyed it so much, that I thought about writing a fic for it! And who else to write about than Lysithea? Anyway, let's get rolling!

Chapter 1: Training

It was a quiet evening in the grand fortress of the Garreg Mach Monastery. The night sky was cloudless, showing off the shining stars and the bright moon overhead with stunning detail. Inside the training yard, there was a single person with long white hair and had a short stature that was practicing her magic against one of the wooden dummies that were lined up opposite to her.

"Hah!" yelled the girl as a stream of dark energy was let out. The beam tore apart the dummy and sent splinters flying everywhere around.

She was Lysithea von Ordelia, the youngest attendee of the Officers Academy and a widely agreed upon "prodigy" of the arcane arts. It was a title she despised with all her existence. The fifteen-year-old girl had spent countless hours practicing magic and studying to perfect her craft. There was also the nature of how those would people would praise her "splendid" crests as well.

"That was an excellent shot, Ms. Lysithea. But your form was off and there were a few imperfections with the casting," a voice said from the darkness. Lysithea let out a squeak and jumped as the sounds of footsteps neared her. Her entire body shook as she turned to meet the voice of the gh-, person, that had startled her. Familiar green hair and a neutral face filled her gaze.

"Professor Byleth...?" she muttered under her breath. Lysithea had barely interacted with the newest teacher of the school due to him teaching the Black Eagle house, with her being in the Golden Deer house. The white-haired girl let out a huff and turned her head away from him.

"It's rude to sneak up on someone else while they train, professor!" she scoldingly said while he walked up to her. She had heard many rumors about how he had saved the heads of the three houses and was personally offered to teach at the academy by Lady Rhea herself. But just how good could this guy truly be? He didn't seem that impressive to her.

"Terribly sorry, I'm just someone who used to being quiet and stealthy," Byleth said with a shrug. Lysithea gave a pout before pondering over what the teacher had said before.

"What did you mean when you said about my casting being off?" she asked in a curious voice. As much as she wanted to ask other questions, like what he was doing out here at this hour or why he had approached her in the first place, but any chance to improve took priority over all else.

The mysterious professor asked her to repeat the spell instead of answering her directly. She did so, firing a beam at another target, creating the same result as before. He went on to show her that the way she held herself while casting the magic was causing the shot to be slightly less accurate than it could be. Also, he noted that the casting itself was fine, but that if she could increase its damage by a margin through better channeling of her mana.

Taking a much smaller circular target used by the archers for practice, Byleth told her to try and hit it using the improvements he suggested. Adjusting her posture and mana control, she fired another shot and instantly could feel more control over the beam. She saw that the dark energy hit the target dead center before it was entirely obliterated from existence. She gawked at the destruction as Beyleth turned to her with the smallest of smiles across his face.

"See? Even the slightest changes can create the largest differences. Though someone who trains as hard as you do, I'm sure you'd understand well enough," he said without much thought. The astonished face turned to him with a look of even greater surprise.

'He's not gonna call me a "prodigy"? Or talk about my crests?' she thought to herself. This was the first time she could remember that someone had praised her for training hard, rather than pointing to her affinity for magic or having a 'knack' for it. He seemed to notice her suprised face as he tilted his head in confusion.

"Did I say something weird?" he asked. This brought Lysithea out of her ruminations as she waved her hands and shook her head in response along with her face turning a deep red.

"N-No, it's just..." she started to say but then lost her train of thought as her words seemed to get caught in her throat.

"Ms. Lysithea?"

"It's nothing! Ineedtogosleepforclasstommorowbye!" she blurted in an incomprehensible blabber as she ran away lightning speed. This left Byleth standing alone while watching the snowy-haired noble speed away from sight.

"Some of these kids are so strange...", the teacher muttered to himself as he continued his walk to the local market, "...now, what type of tea should I buy?"

Thanks for reading!
