The building of a mage's wand is not easy. Rare substances are required, and a vessel must be made that can store great quantities of magical energy. You must gather these things and bring them to me. I have written onto this parchment that which you need, and instructions on how to get it. Bring me exactly what is on this list, and follow my written directions to the letter, for if you do not then when we make your wand things might go... badly.
