Lore
The observers of the cosmos are self-minded beings living in outer space. After the breakout of the spirits, a great mass of energy was released, which manifested into nearby stones like a parasite. The stones became sentient as a result, infusing with nearby gemstones to form their mindless bodies, time after time, they had grown a mind of their own, still, they could not seperate the 'good' from the 'bad.' All they know, is that they live.. Without goal, and without sense.. They roam within space now, attacking anyone and anything, they consider as a threat.
