You're not going to get it because he's gone, and he took the entire "descendants of Allag" mythos with him. It's possible that he's mixed race, but the writers bent over backwards to explain how his ancestor received the royal blood through transfusion, so best anyone can guess is that "Desch" was a Meracydian Miqo'te who served Salina, who was last of the blood descendants of the "original" Emperor Xande. The so-called "waning blood" that had sent the empire into its downward spiral. Considering her FF3 character had one line for 90% of the game ("Oh! Oh, Desch! /comatose"), I can also guess that she passed on her blood and memories that way because, true to inbred royal form, she was extremely sickly and possibly dying, unlikely to survive in the post Calamity world.

But we can ultimately only guess.
