Lore question: What are the original species of Krynn?

The Krynn are said to be a coalition of many species. They originated form their homeworld, where it is said they had many native sentient species. Yet, as far as I know, none were ever named. While it was no problem for the previous games, as there were no in - game species, They have no "native" species, only the ones from game. at least so it seems. What can you say about this?
