I could have sworn in DS9, 'Bolias' is referred to in the same breath as other core planets of the Federation. After the Dominion conquered Betazed, didn't they say 'This puts them in striking distance of Bolias'? Or was that also Berengaria?
A search of Bolius on Memory Alpha only turns up the Bank of Bolias
, which is located on Bolarus IX.
Conquering Betazed put the Dominion in striking distance of Alpha Cenauri, Andor, Tellar, and Vulcan.
