A late Second Imperium Scoutship crashlands on a planet whose TL 4 natives do not fully understand the technology but begin to reverse engineer it. They know nothing about the larger universe around them having been founded by a bunch of religious fanatics in the heyday of Second Imperium and with the subsquent Long Night were completely isolated. Of course, they manage to struggle their way to the 1950s with a space race. How do they react when they find out that the Stars were snatched from them by other humans. Similar to the IW Milieu but one could introduce all sorts of twists in Milieu 0.
