Dark, thick clouds swirl overhead, dimly illuminated by the afternoon sun and the occasional lightnings. Down below, the ship's gears hit the ground, the engines power down and the airstairs descend to the ground. Cold, Moisty air makes its way into the airlock as the doors swing open.
"Kofun V Gentlemen!" - The Sarge announces proudly, as if he had discovered the world himself... - "Be careful down there. God knows whats caused this colony to go silent, but it was probably no rainbows or lollipops... Now, Get moving!"
The team of marines make their way off the dropship and into the brutalist metal structure that stood before them.
A sparkling starport awaited the team inside. The lights were still on and information displays were fully operational. From there, the marines could quickly download the facility's map.
Suddenly, a lone, small maintenance bot crawled out from beneath a table made its way through the entry hall, scooping up what little dirt and water was brought in by the new arrivals.
Inside the passenger terminal was several rows of benches for sitting, accompanied by occasional plants and liquid-crystal displays. In one corner stood a vending machine and some other commercial props while in another corner one could spot a reception desk.
Aside from the door the marines used to come inside, there are 3 other closed doors leading out of this place, as indicated by the map.
