The Kryn Dynasty Composition

Watching the show, I assume that the Kryn Dynasty is an Elvan (Drow) society. So are the different "races" seen in high positions reborn Elves in non-elf bodies? Or are they an integrated mixed society? If an Elven queen dies and is reborn as a dwarf, can she rule the Dynasty?
