"For too many years, humanity was on the backfoot. Reacting to threats, rather than preventing them. Rest of the galaxy was bigger than us. Stronger than us. We were mice, hiding in the shadows, hoping the giants would not see us. No more. Humanity is no longer on the defense. We are the giants now."

— Captain Thomas Lasky
