I feel like calling Ardenweald a Night Elf zone isn’t really accurate. It doesn’t expand on Night Elf lore at all. On an aesthetic level it’s similar, but culturally it’s completely different, and doesn’t touch up on Night Elf lore all that much until you join the Covenant.
I will say, the race that seems like it would mesh best with this zone and it’s inhabitants is hands down, Night Elves.
