Lore wise or not, I'd rather they work on making more fun the current races. The character creator is serviceable but I really wish it had more customizations and while I enjoy the idea of new races (heck I am definitely of the few who wants a Bangaa as a playable race as an example), I prefer they don't bother much with Garleans.

As some posts said, a fake pearl glamour could do the trick (although it might not work with races that have stuff on their forehead as part of facial features).

I won't consider them adding it impossible, you never know but I highly doubt we'll see them any soon considering they still gotta add the female hrothgar
