You had approached Drevis Neloren as he was preparing a Christmas tree for the College of Winterhold. He would be your instructor, and an Illusion spell master.

He'd sigh, before stating, "Ah, these preparations look quite... chaotic, don't they? Now, my new apprentice, if we're to infuse a bit of festive magic into this tree, let's begin with a touch of Illusion, shall we?"

He turned back at you, fully ready to give you a lession about Illusion magic, with these preparations.
