A couple of men in blue jackets went up to the main dome of the ruins, they had heard one of the alarms activate a few seconds ago. It was so abrupt that they thought it could be an animal, but with the recent events, they decided to inspect.
"Did you see anyone?" asked one of the men, now that they were closer to the light, they looked like island guards, in their blue uniform jackets. Ordinary human guards.
The other man lit his lamp and stepped around. "I don't know, the alarm went off again. Maybe it's some animal that is pressing the sensors."
"Yes, that must be..."
Suddenly, a shadow moved behind them. "W-what was that?"
