The star may be called Nodapar and its single planet may officially be Bashois, but everyone in the cluster calls them Crapworld. There was originally a fair amount of hope for Bashois; it was densely covered with life, and some of the largest, most complex life found anywhere at that. Colonization began in earnest, but after a few decades the ecosystem seemed to fight against the humans who had settled there. The ways in which settlements were sabotaged and attacked led to speculation that at least one species had reached intelligence, but the military, once it got involved, didn't care about such details. Their expeditionary force had been defeated, something that had yet to happen, and they decided revenge, not study, was in order.
The planet was (mostly) evacuated and orbital bombardment commenced. Even the non-military, finding offence at defeat of humanity by some wretched aliens, got involved, dropping toxic waste on the planet. The idea of using the planet as a dumping ground for the system gained traction, more due to bloody-mindedness than economics or anything else.
Today the planet is a mess, its ecology a shambles. The idea of using it as a dumping ground has expanded beyond simply physical waste and a population has grown as prisoners and opponents are dropped off.
