Was sent to go kill a "wizard", turns out he'd turned himself into a floating crystal, craziest shit I ever saw.
Obviously when he offered me work, I accepted. He gives you a mini questline, which ends with you choosing to become a crystal and live forever with him [YOU DIE GAME OVER] or just remain his apprentice and get access to his master level enchanting training. I chose the second one.
I'm gonna get enchanting to 100 in this playthrough and make myself some overpowered gear without abusing fortifying intelligence potions.
