Glaring Nightmare was the name of one of the rowdiest radical groups present in the Orion belt of the Milkyway galaxy. They were nowhere near the strongest, but their ability to cause a mess was unmatched. Even Xyrans would have a hard time beating them when it came to making messy situations even messier.
Unlike other groups in their clique, they openly did things that would have deemed them as psychos. Including but not limited to throwing each other out in the space without so much as a space suit just because they got bored. Yeah... not such a great way of curing boredom.
They were more like a sorority group being high as fuck and their pranks going out of hand than a terrorist group. Their only motive was to spread as much death and destruction as they could... that too in as sadistic of a way as possible.
