I have only seen HUMAN factions. Or I'm just not looking hard enough. But what if elves were real? Or the Dwarves? or other D&D races at the time of earth's poplution limit reached? And they also sent ships out into the galaxy to live?

Here are few races I would love to become factions.
Elves and Dwarves

Vampire? Werewolves? Orcs? Trolls? Dark Elves? Wood Elves? High Elves? Gnomes? Halflings? Dragonborn? Drow? Goblins? Mermaids? Kobolds? Tiefling/Demonin ancestry humans?, Elementers? Centaurs? Etc?????
