There is very little information available about life in the great "Mothercraft" or Lightships of "The Galactic Federation Of Light" (GFL) that are stationed in proximity to the Earth.
These Mothercraft are truly "Great". The Pleiadian ship "The White Winds" is a disc shaped ship that is as great in diameter as the distance from coast to coast in the USA, and has about 47 levels or decks. Other "Ships Of Light" are smaller, but the Ashtarian ship, "The Phoenix", is still several hundred miles in diameter. Life onboard ships of this size is like living on a small planet, and shuttlecraft or Vis Cars are needed for any long distance travel within them.
Those that we term "Negative ETs" are not of "The Galactic Federation Of Light", and were invited in by the American military back in the early 1950s to trade for their technology in return for being allowed to establish bases on the Earth and to abduct people from time to time to harvest their genetic material, for the purpose of repairing their DNA. Their two races; the "Grays" and the "Reptilians" have now left our planet. The Grays left around the turn of the Millenium, because they could no longer tolerate the high level of pollution on the Earth, and the Reptilians left more recently.
