Here is the plot: in a society close to earth and humans, but with medieval-like technologies, there is a group of people that is regularly migrated to a new place where it should installed itself. This group can bring material and tools but in the end, it should work by itself with the resources of the new land. The group could have any size between 5 000 to 20 000 people in it, the size will depends of what is possible to do.
So this looks like rather easy migration, but here are the problems:
- The group will go in an uninhabited area: it will have to build everything from scratch
- The group will go to "non-nice" areas: in the plot, "nice lands" with temperate climate are already occupied. What we called desert (either sand, mountain, snow... deserts) is the targeted zone for the migration
- The group will have to build some sort of sustainable system (not just take the few resources in the new region and then move again)
Now the advantages:
- All social and economic organization are allowed
- If everyone is focused on getting something to eat, then it is ok. The group is not supposed to build cities and medieval comfort fastly
--------- EDIT ---------
Some precisions about the plot:
- The polar desert could be either Antarctic or Arctic style
- The medieval group could have some modern "permanent" technologies. For example he knows about phones but have none, and he could be vaccinated (but could not take medicine with him)
- The group only needs to survive there, and not to have enough means to re-build a civilization
My story's plot would be that the group is sent to a region similar to Arctic (or Antarctic). But how could I justify this region to be appropriate, especially about the capability to have a reliable and durable of source for feeding this group?
Final question: How could a group of 5 to 20 thousand medieval colonists go to and establish themselves in a previously unpopulated polar desert and survive by their own means?
