The Head Elder appeared calm and confident, but deep inside, his mind has gone to a wild mess. The fact that a spy had infiltrated them for who knows when. Just how much of their internal meetings had been secretly recorded? The information and technology they have secure, and is the real sixth Elder even still alive?
No wonder why the Ancient humans had been so silent for how many years!
They were a selfish race who craves intelligence, to the point that they are responsible for the sudden disappearance of promising humans. Extracting their talents and intelligence before dispatching them like dead animals.
And no matter how the Guardians would try to capture them, the suspects would always be one step ahead. Before they could even send their soldiers, the Ancient humans could swiftly react and escape! The scent, camera recording, footsteps, you name it - not an ounce of traces are left behind.
