For the Lux, victory had basically already been achieved in the New Dawn system, and so all of those who remained and survived the incredible supernova of the system's sun were in a state of celebration while their engineers repaired their ships to varying degrees.
However, unbeknownst to them, their time was limited. With their ships so badly damaged, their communications were next to nothing and so they couldn't even contact each other throughout the system, save the few people who had talents that allowed for such a thing.
So, when a single human rampaged every Lux ship he came across, word didn't even spread to the others. They were completely ignorant of their coming, inevitable demise.
For the next two days, the space that once was the New Dawn system became a Lux graveyard.
