considering the kingdom doesnt exist yet
and that she was already confirmed as originally being from Cloudsdale
makes sense to me
I didn't know about the Cloudsdale thing :I
For some reason I thought it's were a type of pony, with rainbow manes and whatnot originated, or there's a huge amount of them living there, like the Crystal Kingdom I mean.
You don't really see any other Rainbow Ponies honestly :I
