On the Forge world map, “Impact,” it has a building in the center with a big rock in the middle (maybe for mining) but that’s not the point. It has a really creepy ambience to it. Also, in the distance is a big planet (or asteroid) that is half-way destroyed. One last thing, what happened to all the miners? Where’d they go? Did they just abandon it or were they killed by some unknown entity? Please explain if you know. 
Just play the story, it explains it all.
Played it, but that isn’t that same map from the story right? On the story map it was much bigger, on this map the level is small. Unless I’m missing something.
