In real life it's dwarfs and elfs but in Tolkien's it's dwarves and elves.
You're right. I can't remember the source for this, but Tolkien basicially threw down with "'Dwarfs' looks dope. I'm a gonna spell it 'dwarves'" once-upon-a-time.
This was before looking dope was actually still bad and before it was good.
It was also before bad was good and bad was just bad.
