Billy Meier further described how the Pleiadians, descendents of the Nordic looking Lyrans, had migrated between a number of star systems before finally settling in the Pleiades constellation:

"The ancient history of the early Pleiadian ancestors in another home sun system was also described and how they came to travel to the Pleiades. A much earlier migration to this solar system is also described and how and why it failed. The one third survivors of the Pleiadian ancestors' original planet, after its devastation, evolved a new technology, and designed and built the great-spacer evacuation arks in just 900 years, and began to launch them everywhere for many hundreds of years more. The extraterrestrials visiting Switzerland are the descendants of one of those space arks which occupied one of the three levelts engineered for human habitation, in one of the sun-systems in what we call the Pleiades today. They have experienced great gains and great losses many times over since that time. In a very real sense, we are descendants of their earliest colonists attempting to settle in this solar system, together with an assortment of aborigines and human exiles from a number of places."

The particular star system from which Meier's Pleiadians originate is Taygeta and the main planet is Erra. The Pleiadians from Taygeta identified Meier as one of their chosen ‘representatives' with a mission to bring the truth of the extraterrestrial presence to humanity. Semjase, the Pleiadian female who made contact with Meier, described the Pleiadians as follows:

"We are neither guardians of Earth beings nor God-sent angels or similar. Many persons suggest we are watching over Earth and her beings and would control their fates. This is not true, because we only perform a self-selected mission which has nothing to do with supervising or regulating Earth fates. Thus it is wrong to expose us as superterrestrial messengers and guardians."

The Pleiadians identified a key aspect of their mission is to warn humanity of the Grays which they described as follows:

* There are also different life forms that have acquired much knowledge and have freed themselves from their environment. They travel through space and occasionally come to Earth.

* Many of them are rather unpleasant creatures and live in a type of barbarism that frequently is nearly as bad as the terrestrials.

* You should be aware of them because they often attack and destroy everything that gets in their way.

* Many times they have even destroyed whole levelts or forced their inhabitants into bondage.

* It is one of our missions to warn the people on Earth of these creatures.

* Let this be known to the Earth people because the time is approaching when a conflict with these degenerate human creatures [Grays] becomes unavoidable.

According to Collier, the Grays and Pleiadians are involved in armed skirmishes in the solar system and other systems such as Sirius B. Other key aspects of the Pleiadian mission according to Meier, are to assist in the uplift of human consciousness and to promote the unity of religion. Significantly, the Pleiadians were dismissive of the claims of many other contactees such as Adamski, and thereby implied some exclusivity in relating the truths and dynamics of the extraterrestrial presence. Interestingly, Collier claimed that some Pleiadians groups such as those from Alcyone operate with ‘hidden agendas', while those from Teygeta (e.g., Meier's Pleiadians) are described as genuinely assisting humanity. Despite the possible ‘hidden agenda' of some Pleiadians, most testimony and evidence points to Pleiadians in general having positive interactions with humans, and that they do much to assist in the elevation of human consciousness and assisting humanity in finding freedom from Gray/Reptilian influence. In conclusion, the main activity of the Pleiadians appears to be helping humanity find freedom from oppressive structures through education and consciousness raising. The Pleiadians can assist in find global solutions such as universal human rights, participatory democratic systems, the evolution of human consciousness and global education.
