BG3, I believe, won't have a suitable setting for adding such a race
Question is: Would any race on nautiloid seem anyhow more odd that our curent bunch of Compaions?

I mean ...
Dude with really strange magic inside, a Gith, a Vampire Spawn, a Werewolf(datamining), Warlock and his Cambion patron ... if nothing else, it seems to me that the Absolute was trying to gather as much rare specimens as possible ...
Maybe they are researching possibilities of ceremorphosis, maybe they are looking to infiltrate every and any society possible ... and maybe we would never know why they kidnapped our super-special-rare custom Tav.

What im trying to say is that no matter how exotic race we pick, from whole DnD lore ... i highly doubt that our character would feel anyhow more special compared to our companions.
And therefore ...
Any race would be explained simply by stating: They kidnaped me aswell.
