"Alright...
Before any of you decide to fall asleep with your eyes open, today's topic is Spell Imprinting and Memory Crystals."
Noel stood at the center of the lecture hall, one hand tucked into his coat pocket, the other lazily holding a thin piece of chalk.
His expression, as always, looked mildly inconvenienced by existence.
A few students straightened instantly.
"Spell… imprinting?"
Someone in the third row murmured.
"Yes."
Noel replied flatly.
"The creation of crystal-based storage units capable of recording, replaying, or containing a spell for later use."
He turned and drew a simple circle on the board.
"At its core, this is structured mana encoding."
He paused.
"Think of it like writing."
Silence filled the room.
"Except instead of ink..."
He continued, tapping the chalk against the board.
"...you're using mana.
And instead of paper, you're using crystal lattices."
A hand shot up.
"Yes."
A brown-haired student stood.
