"David, what's wrong?" Elizabeth said as they stood before the hanger door. David was messing with the panel and turned to face her. "It seems that these doors were intentionally disabled. No matter what I do, I can't get it open. It appears to be damaged." Elizabeth walked up next to him, looking over his shoulder. The panel itself was intact, but the symbols to operate it looked melted. "It looks like some kind of corrosive material caused this. See the burn marks?" she said pointing at the outer edges of the hole. David examined it more in depth and replied "Why just this door though? All the other hangers are empty and open. Why prevent access to this one?" he said. They stared at the panel for a few seconds and decided it was time to move on. Elizabeth wasn't really concerned with the hangar doors. There was so much more to look at throughout the city. Elizabeth felt the hairs on the back of her neck stand up as they walked away from the hanger, but she shook it off and pressed on.
They decided to check out the dome structure in the middle of the city. It was massive and had the characteristics of a place of importance. Maybe this was the central hub of the city. The doors to the building were open, so they didn't have to worry about finding a way in. Inside the building was a big chamber. In the center were four gigantic throne like placements set next to each other. And around the outskirts of the chamber were what looked like seating for many people to look down upon the thrones. Almost like an arena. Wait, she thought, not an arena, but a government building. Maybe this was where decisions were made or court was held. Something caught David's attention and he walked to the center by one of the large seats. He was looking at something on the ground as she took in the rest of the area in awe. "Elizabeth, look at this." He said, his voice echoing throughout the chamber. She walked over to where he was and saw what he was looking at. A large hole went into the floor behind one of the thrones. They both peered into it, careful not to get to close to the edges. "Something melted through this floor. Look, it goes down throughout the levels below us. And the burn marks around the edges of the hole are just like the marks on the control panel at the hanger." David said, pointing around the edges of the hole. "It could have been some kind of chemical spill. Molecular acid has this kind of effect, but not as extreme." Her voice echoed. Something else caught David's attention in the dark corner of the chamber and he walked over to it. "Elizabeth." He said as he knelt down. "Look." She walked over and a chill ran through her when she saw what he was looking at. Curled up on the floor of the chamber was a crab-like creature, with a long tail. "What is it?" She said as her wound on her stomach began to itch. "Whatever it is, it's been dead a long time. There is nothing left but a skeleton." David replied as he tried to pick it up from the tail. It crumbled to dust in his hand. "Maybe it was a pest like a rat on earth, or a roach." He stood up dusting off his hands. "David, let's get out of here." She said as she scratched her stomach. "I don't know what happened here, but I have a feeling that whatever it was, it wasn't good." They headed for the door, when something on David's suit started to beep. He looked at the bracelet he was wearing and looked at Elizabeth. "The ship has been breached. I rigged it to notify me as a safety precaution. Something opened the hatch and is now onboard." David said, as they both rushed for the door. Elizabeth remembered the Engineer back on LV-223 and how violent it was. If it was anything like that one, they were in trouble. They couldn't afford to let it destroy the ship. It was there only ticket off this planet. If they survived.
