1981 - When the Pleiadian/Plejaren extraterrestrials averted a hostile takeover of Earth.

These extraterrestrials were accustomed to war, and were willing to kill the inhabitants of the planets they had chosen for resettlement in order to gain living space for themselves. Thankfully the Pleiadian/Plejaren extraterrestrials discovered this and intervened in time to avert a catastrophic outcome for us.  

According to the information it involved a large scale operation where the Pleiadian/Plejaren deployed their personell not only from their home planet, Erra, but they also from their manned stations here on Earth as well as their manned stations in other worlds. Those deployed from their stations here were temporary replaced with other personell belonging to their federation, with people from the Wega and Lyra region. 

It’s something  Guido Moosbrugger also wrote about in his book AND YET ... THEY FLY! page 325 to 326 in a chapter he called ‘Lucky Once Again’, and below is the version from the German contact notes.

What’s further interesting is that at the time, 1981, a tri-solar systems with planets was considered unlikely to the degree of bordering on science fiction. But this opinion changed when in 2005 the first discovery of a  tri-solar system with a planet was discovered. Some info: 

AI Overview

 Before their actual discovery, the existence of planets in triple-sun systems was considered highly unlikely and bordering on science fiction by many, due to the extreme orbital instabilities caused by multiple gravitational forces. While theoretical models recognized that "hierarchical" setups (where stars are far enough apart) could theoretically allow for stable orbits, the chaotic nature of three-body interactions led most to believe such planets would be quickly ejected from the system

First Planet Under Three Suns Is Discovered July 13, 2005 PASADENA, Calif.

An extrasolar planet under three suns has been discovered in the constellation Cygnus by a planetary scientist at the California Institute of Technology using the 10-meter Keck I telescope in Hawaii. The planet is slightly larger than Jupiter and, given that it has to contend with the gravitational pull of three bodies, promises to seriously challenge our current understanding of how planets are formed. 

In the July 14 issue of Nature, Maciej Konacki, a senior postdoctoral scholar in planetary science at Caltech, reports on the discovery of the Jupiter-class planet orbiting the main star of the close-triple-star system known as HD 188753. The three stars are about 149 light-years from Earth and are about as close to one another as the distance between the sun and Saturn. 

In other words, a viewer there would see three bright suns in the sky. In fact, the sun that the planet orbits would be a very large object in the sky indeed, given that the planet's "year" is only three and a half days long. And it would be yellow, because the main star of HD 188753 is very similar to our own sun. The larger of the other two suns would be orange, and the smaller red.

So below is the information the Pleiadian/Plejaren extraterrestrials gave to Billy Meier 24 years prior to our first actual discovery of a tri-solar system with a planet. And 1981 was at a time when a  triple-sun systems was considered highly unlikely bordering on science fiction by many.

Part quote: 

Billy

 Aha, and what's the situation now: Why have all the stations been cleared, and where have your people gone?

Quetzal

 37. You've never asked about things like this before. 

Billy

I know, because I'm not curious about these things either. But it would be interesting for us to know why such movements of people are happening with you, or is that a secret? 

Quetzal

38. It is not a matter of that kind. 

39. I am only surprised by your question because you have kept away from such matters until now. 

40. We had to withdraw all available forces not only from Earth, but also from many other worlds, including Erra. 

41. We need all available forces because the population of an entire system, which comprises 16 inhabited planets and three suns, has prepared for a space traversal in a warlike manner because their system is facing destruction. 

42. The goals of these people still accustomed to war are the habitable planets of various constellations, including the SOL system, and therefore Earth.

43. These rather inhumane human life forms are willing to kill the inhabitants of the planets they have chosen in order to gain living space for themselves. 

44. On the one hand, our forces are preventing these life forms from realizing their plans through a breakout into space. On the other hand, however, other forces of ours are systematically relocating the populations of the various endangered planets to uninhabited but easily habitable areas, while yet another part of our forces is searching for new habitable and suitable planets on which the remaining of these people can be settled and resettled.

Billy

Incredible, but can't the Lyrians and Wegans help you with that too?

Quetzal 

45. We have also involved many of their forces for this task; another part of them will take over the tasks on Earth at the end of this month, as I explained to you earlier. 

Billy 

I know, you mentioned that Menara's father, her brother, and her sister, along with 35 others, will come here.

Quetzal 

46. That is correct, but these 38 people only represent the first wave that will take over our own station and our tasks. 

47. Our station and the other two, in America and Asia, will be fully staffed with our allies.

German original:

Billy

 Aha, und wie steht es nun damit: Warum sind alle Stationen geräumt worden, und wohin sind eure Leute abgezogen?

Quetzal

 37. Du hast noch nie nach solchen Dingen gefragt.

Billy

Weiss ich, denn ich bin in diesen Dingen auch nicht neugierig. Es wäre nun für uns aber einmal interessant zu wissen, warum solche Verschiebungen von Menschen bei euch stattfinden, oder handelt es sich dabei um ein Geheimnis?

Quetzal 

38. Es handelt sich um ein solches nicht.  

39. Ich bin nur verwundert über deine Frage, weil du dich bisher von solchen ferngehalten hast. 

40. Nicht nur von der Erde mussten wir alle verfügbaren Kräfte abziehen, sondern auch von vielen andern Welten und so auch von Erra. 

41. Wir benötigen alle verfügbaren Kräfte, weil sich die Bevölkerung eines ganzen Systems, das 16 bewohnte Planeten und drei Sonnen umfasst. auf eine Raumtraversierung vorbereitet hat in kriegerischer Form, weil ihr System dem Untergang anheimfällt.
