Emilia paced back and forth at the front of the classroom, her heels clicking softly against the floor. Her sharp eyes scanned the students, making sure they were paying attention as she spoke. Her tone was firm, yet there was an undercurrent of passion in her words, a clear indication of how much this subject mattered to her.
"Mana," she began, stopping briefly to face the class, "is the essence of the world. It exists in everything tied to life, whether it's the plants, the animals, or us. In its purest form, mana is called Purus. It's untainted, raw, and can be converted into any type of elemental mana."
She gestured toward the windows as if pointing to the unseen spirits beyond. "The spirits all around us play a role in this. Some transform Purus into elemental mana, while others do the reverse, turning elemental mana back into Purus."
