I'm actually beginning to interpret Jaune's character as the Aura amateur. Which means we'll know more about Aura via him.

Meanwhile, Ruby is the Dust amateur, and Weiss will be teaching her some of the ways to use Dust in later seasons.

Collectively, Jaune and Ruby are the method through which Monty can begin the worldbuilding, due to their inexperience in certain fields. (ie. Jaune doesn't know the Mistral Regional Tournament or whatever)

That practically means all the info we need to know about planet RWBY, will be told to Ruby and Jaune.
