Below the surface of the city, a Space Marine was sitting against the wall. He was inside of a specially designed cell to hold soldiers like him. When he heard the faint sound of an army above, he breathed a sigh of relief. Unfortunately the Tau had disabled the tracking device in his armor, so his brethren above didn't know he was down here. The Tau had treated him pretty well for a prisoner, except for the mental suppressors and bindings. He heard the door begin its unlocking mechanism, and he looked up; The lights brightened up as well.
The Ethereal walked in the small room. "Your friends are searching for you, but they won't find you. You'll be staying here with us for a while." He stopped to listen to his radio. A look of horror crossed his face; the Space Marine smirked.
"It seems that my brethren are doing a better job then you expected." He laughed a little.
The Ethereal's face turned from horror to anger. He looked into the face of the soldier, which was obscured by a hood over his head.
"Don't be so sure." He turned and ran out of the room. The door quickly closed behind him, and the lights dimmed. The Space Marine put his head against the wall just as the locking mechanism engaged. He was left in darkness once again.
