Black Hole Sun

Encyclopedia description
"A famous hub of technological expertise before the Jump Gate shutdown, thanks largely to the people stationed there to stop the influx of Xenon activity from neighbouring Xenon Sector 472, Black Hole Sun now enjoys an extended era of peace. Still, its people have remained busy, attempting to build a self-sufficient community in case history repeats itself.

Though the system finds itself cut off from Argon Federation space by the Antigone Republic, a constant stream of supplies pours into the area, with the federation desperate to show that no colony of theirs will be left to fend for itself." -- X4: Foundations encyclopedia
