Legend
To be clear, those "evils" are less "going to the big city and losing their innocence" and more "getting slaughtered by orcs."
I think the Yoda comparison above is a good one. Yoda's species doesn't matter in the grand scheme of the galaxy. Not only do they lack lore, but they don't even have a name.
Yoda himself, however, and a few other members of his species? Super-important.
But, I think you are hitting the nail directly on the head.
Yoda's species doesn't matter. Yoda matters.
But, if I am building a star wars world and I start saying that Yoda's species is one of the four most important species in the galaxy... because Yoda matters... then I'm talking nonsense.
Sure, Sam, Frodo, Merry and Pippin mattered. But that doesn't mean Halflings matter. And if we want halflings to matter... they need to have actual lore.
