But is Bolarus the home world of the Bolians, or just a world which some Bolians are from? Did any character ever state outright that "Bolias" or whatever was the world on which Bolians evolved? Some humans are from Mars, but Mars isn't the human home world.
This kind of connecting of actually unrelated facts reminds me of the alleged "Daedalus-class" model that was in Sisko's office. Everyone accepted that that model was Daedalus-class, despite no dialogue ever connecting the class to the model. That's how fanon spreads, and fanon is interesting, but too many fans latch onto fanon "facts" as if they were incontrovertible.
