Nova Scorpio

Nova Scorpio was a supernova that happened in the Third Millenium and is thought to be caused in some way by the intelligence that created the Monoliths. The planets orbiting the star that would become nova scorpio exploded one by one before the star collapsed into a supernova. This is speculated to have been caused by the Monoliths or the intelligence that created them. Some speculate that it was possibly a necessary thing that they would have to do to foster intelligence, like Lucifer, or even a way to wipe out a failed attempt to create intelligence.
