Ten Thousand True Bloodlines Codex

I read King of Gods(Great story by the way) and got kind of annoyed that we didn't see many of the 10,000 Ancient Races in the story. Therefore I am going to try to make my own 10,000 True Bloodlines to maybe have if I ever bother to write a book with them in it. Also I just kind of want to prove that it is possible to do. If you have any thing you think could work you are free to add any comments and I will try to incorporate them.
