If there were, we may never know because 90% of the First was destroyed completely, including the region they are supposed to be from. We don’t see Lupin, Namazu, Sylphs, Kojin, Vanu, Vath, or Qiqirn either. Doesn’t mean they only existed on the Source.

The only races that we know should only be on the Source are the Ixal, Ananta, and dragons.
