Some Grounder Clans, such as the Woods Clan, Sand Clan, Boat Clan & City Clan, may have kept in contact with each other and the City People started a trading program to get other Grounders to bring in Sky People. The Grounders may also have always known about the Sky People while they were in the Sky, as that was what happened in the novels, but they do not always follow the same plot.
