In my story, I'm potraying the Elves as both a divided people(high,wood,and dark) as well as a species that is slowly dying. Example, the High Elves, though they are the most magical and possess eternal youth, their attitude and suppose superiority has rendered them sterile and are unable to keep their bloodline and culture pure. The Wood Elves are unable to use magic(genetically incapable) they live in environments that possess very little resources, and are constantly under attacked by brigands. Dark Elves are marred due to their former alligence to the Dark Lord, they want to change, but are incapable due to prejudices with humans and other elves.
I was wondering if there is more I can do to deconstruct the "perfect" Elf stereotype or is this good.
