Extinction Cataclysm

In the year 2356, humanity discovered through the 'Deep Space Eye' array that the 'Gliese 667' system in the Orion Arm was losing its luster. Not an explosion, not a collapse, but like a drop of ink into clear water, it was being devoured by an unanalyzable 'Gray Silence'. All detection signals went unanswered. Initially, astronomers considered it an unprecedented astronomical phenomenon. Not until three years later did the 'Gray Silence' engulf the first human outer colony, proliferating from its matter and expanding by 0.003%. Panic began to spread. People named this incomprehensible phenomenon—'Extinction Cataclysm'. Our story begins here.
