"In this first year we cover a range of different things, not all of it will directly relate to charms but all of it will be important for this subject and all of your other subjects later on. Now this first lesson will cover the basic principles of casting magic, this lesson is something that will obviously be useful in every wand based subject and such a lesson is taught every year in whatever subject you have first that requires a wand. Luckily it has fallen to me this year which is great because I love teaching this base principal and would honestly like to do it every year but scheduling denies me this."
