The Castle of the Border

This is basically a Golden Age Sci Fi set up. A long lost human colony has been found. The PCs are members of the various peoples descended from the lost colony ship. As this is a Golden Age Sci Fi setting the lost colony ship crashed on a world with a healthy ecosystem and the human colonists survived, and so did the ecosystem.

The colony ship came to grief while flying in hyperspace. This caused a time-jump backwards in time. So, although the colony ship has only been lost for seven years, the colony ship crashed on this world thirty-five hundred years ago.

The PCs are locals. They are aware of the fact of higher technology, but know nothing of the details. The recent scout base/anthropological exploration center is a boon. A chance to relearn the skills of the ancestors. The problem is that, as test subjects, they are to be studied, not taught.

The anthropologists want to study primitive humans. If you try to do that on Earth, you either have to go to a museum or interview people about long dead relatives that neither they nor you ever met. There is no way the anthropologists want the locals to regain technology.

Basically, it's a struggle to steal knowledge or keep it from being stolen. Thief/Spy skills will be the main focus.
