Why would "barbarians" be envious of "civilized accomplishments"? In the real world, "civilized" people killed off "barbarians" so they could take their stuff and/or get slave labor, which makes the barbarian's retaliation actually rather just.because they were made that way. But I use them as an allegory for barbarians at the gates of civilization envious of their accomplishments and even if they win they will not have what the people they conquered had because they don’t have the knowledge to maintain such a civilization or city.
I used most races like they were used in fairy tales.. as allegory. There is no Darwin or genetics. Animals talk. Unicorns are in forests.
Most fairy tale non-humans were one-off trickster fey, not whole races. If they were an allegory for anything, it was for the humans to stay on the path, follow the rules, don't take (magical) shortcuts, be kind to people you meet on the road (they could be a fairy in disguise), and don't make bargains with strange people, and if you do, don't break your end of the bargain.
Unicorns were incredibly vicious creatures that impaled elephants on their horns and represented male virility, which is why they liked virgins.
