Bolarus
From FEInfobase
A Blue Giant star with 9 planets in orbit around it. Bolarus IX is the homeworld of the Bolian people.
The system was one of the first to be consumed by the advancing Borg at the war's onset. The Borg wanted to get a foothold into Federation space from which to launch attacks at the core systems. Starfleet was forced to retreat and the Bolarus system fell with little resistance.
As of 2409, it was unknown what had happened to the Bolian people.
