I've always been more into Warhammer fantasy than WH40k, but I'm no expert which will be obvious by this post and question. My favorite race in Warhammer fantasy was the High Elves and as such I've always had a keen interest in the Eldar of WH40k. Thus, my question is probably geared toward the lore buffs here, hoping for some enlightenment. What is the difference between the High Elves and Eldar? Are they the same race just fantasy vs. sci-fi?
