Beginning in 1975, Meier allegedly began his official contacts (“official” in that evidence was to be provided publicly, unlike earlier contacts), communicating both directly (face-to-face) and by telepathy with a core group of the Pleiadians/Plejaren, or Errans as he also refers to them (Erra being their home planet), who gave their names as Ptaah, Semjase, Quetzal, and Pleja, among numerous others.
