Forged Destiny [Book 7: Ch. 13]

"You're quite easily the strongest Blacksmith alive. The strongest in all of Remnant. No one can match your skill, your potential. I could travel the world and never find a Blacksmith your equal. Any sword you create would be especially powerful." She spread her arms. "I am Raven Branwen, the most powerful person in the world. No one can match my level, but the sad truth is that no equipment can match my level either. My blade has served me faithfully for many years and levels, but I've outgrown it. I need something better. You will create something better."

Ah. Suddenly, it made a lot more sense. I'd never really considered it because I was limited by what materials were available and, for the most part, any Blacksmith could work with them, but I was the best Blacksmith in the world at this point.

No wonder Ozpin had wanted to keep me close to Beacon, even after I'd been expelled.
