When Valarinth finally got to class 3A she entered the room and stood by the desk.<br/>"Good afternoon class, I am Valarinth, the head of this school and I shall be teaching you in the absence of your original teacher, Miss Jnfly whom appears to have gone missing.  Now, I'd like to begin this evenings lesson with silent and gesture free spell casting.  If you'll open your textbook titled 'Performance of Magic: A lesson in what's Rite' to page 476 we shall begin our lesson.  For those of you who don't have a book, here..."  She motioned her hand across the room and turned some of the student's writing utensils into identical copies of the book she was holding.<br/><br/>"You see being able to cast a spell without words or movement is a very handy thing in transmutation, say for instance if someone transformed you into a pebble.  That can't move or speak, so unless you find someone who can recognise what you are and have the ability to change you back to normal you're going to be stuck like that, possibly forever.  Silent and gesture free spells require a lot more mana, but the results are worth it and often quicker than the spell was originally meant to take up in a casting.  If you're good enough, it may only take a mere moment."  She then goes on to quote some literature from the book, some general algorithms for working out how to make certain spells silent or gesture free then says.  "Now try a silent or gesture free spell to levitate your books off the desk.  It might take a while, but you'll get there."  She now walks around the class, watching their efforts carefully.
