I am the Dragonborn of legend. I defeated the world eater, effectively saving the entire world. I ended a civil war, which means I helped protect/over through Whiterun. I captured and then released a Dragon at Dragon Reach palace. I am the Archmage. I wiped out the Dark Brotherhood.
Yet still I was greeted by said line. "You're not seriously considering letting him join master? I've never even heard of this outsider." --- Would You Kindly.
