Sky People

Sky people Sky people is the name given to the humans that lived on the ark. They are given the name by the grounders because they lived in space. However it is not only the grounders that know that humans had fled Earth 97 years ago, this is shown in season 2 when Jaha is taken care of by a family of three who eventually betray him so that they can get a horse and reach "the city of lights". The woman remarks: "there is a bounty on sky people" so it is unlikely that it was the wood clan that came up with the name.
