On the top floor of a magic tower in Douglas Magic School.
Sitting in the classroom for senior apprentices, listening to Vilnia's Basic Elements, Chely's mind wondered a bit. Basic Elements was part of a series of courses introducing the apprentices to the world of elements.
Chely heard that both Heidi and Layria had now become real arcanists with their more than ten arcana credits.
"…This is all for today's introduction of the ancient element theory. Now let's move on to the contemporary system of elements built upon Her Excellency Hathaway's atom theory. What is an atom? An atom is the smallest unit in the world, that cannot be further divided. Each kind of atom is an element, and the properties of different atoms vary. Atoms can react with each other and thus create all the matters in the world. Atom theory is also very important to courses including Potion and Alchemy."
