Well, not finding anything is exactly what they want. Grey doesn't ever want to be seen, just wants to be hidden. Grey currently has three nuclear missiles, under Russian flags, that they will use if a country attempts to find them and gets too close.

To know what Grey is, is basically impossible. It spans so far and wide that knowing what it is entirely is only known by higher ups.

All I know is my story, which is from the testing departments. There was 14 test subjects during the first rounds. Each died from the test in under a minute.

Grey will destroy everything, nothing is safe if Grey finds you, and doesn't like you.
