Semjase Tenia 330 años en 1975, lo que corresponde aproximadamente a una Tierra de 33 años de edad, si es proporcional a nuestro entendimiento, ver Los siete periodos principales en la vida humana. Mide alrededor de 1.7 metros (5.5 pies.) de altura  a es una mujer delgada, joven y guapa con piel clara, ojos azules y cabello rubio claro, fino .
Sus lóbulos de orejas muy largos y algo adelantados  son una de las pocas características o rasgos raciales especiales, y distintivos que tiene. Constituyendo la principal diferencia anatómica visualmente aparente, en comparación con una mujer de la Tierra. Además de esto hay una proporcionalidad física general y generalmente mejor, más adecuada, superior, que no es necesariamente inmediatamente evidente. A todos los efectos, se parece a una mujer de la Tierra. Todos los Plejaren e incluso muchos de los humanos de la Plejaren Federation se parecen un poco, vease Los 7 principales factores en la vida humana.
Debido a su conocimiento excepcional, que sobrepasa el promedio de incluso su hogar-mundo(s) población, ella ha asumido el rang designado Plejaren de medio-Jschrjsch, que puede significar 'mitad-reina de la sabiduria' o una 'mitad-diosa', como se les llamo anteriormente en la tierra. Habiendo dominado varias ocupacionesy se ocupó de varios asuntos en nuestro planeta, años antes de comunicarse con Billy Meier, que sucedió por primera vez el 28 de enero de 1975, se convirtió en uno de los extraterrestres mejor orientados También con respecto a nuestra situación en la Tierra, Earth, véase Interview with Billy (1988) - 1ª Pregunta -respuesta - 'Situation on Earth', antes de su accidente.
During the period of time from February 1965 until June 1973, she stayed in the Universo DAL with Asket's humanity. After her return from the DAL Universe to Erra, she came to Earth in July 1973 and continued to carry out the task she had performed here earlier in a hidden station. Of all the Earth languages, she has only mastered German and learned no others, other Plejaren personnel have masters others. In November 1984, Semjase finally had to leave the Earth for health reasons.
Her field of work was exclusively restricted to the European area. She had no authorisation whatsoever to become involved in any matters outside the region or for that matter establish contact with any Plejaren work groups in other areas of the planet, outside of Europe, neither in America nor Asia, other Plejaren personnel have been.

Semjase name meaning, origin and pronunciation

|Excerpt from the 475th Contact Report of 26th November, 2008||Auszug aus dem 475. Kontaktbericht vom 26. November 2008|
|Semjase is a very old name that we Plejaren adopted from the Ancient Lyrian dialect, it means “The Demigoddess”.||Semjase ist ein sehr alter Name, den wir Plejaren aus einem altlyranischen Dialekt übernommen haben; er bedeutet ‹Die Halbgöttin›.|
|If the E at the end of her name, as I spoke of in the English language example is pronounced I, then there is a very bad misnomer.||Wird das E am Ende des Namens jedoch als I gesprochen, wie das z.B. in der englischen Sprache getan wird, dann ergibt sich daraus ein sehr böser Unwert.|
|“Sem”, from Semjase means in the Ancient Lyrian dialect “Half” while “Jase” means goddess, but “Jasi” means “Bane Goddess”.||‹Sem›, gemäss Semjase, bedeutet im genannten altlyranischen Dialekt ‹Halb›, während ‹Jase› Göttin, ‹Jasi› jedoch ‹Fluchgöttin› bedeutet.|
|Hence, if in the English language the E at the end of Semjase is spoken as I, so therefore Semjasi, the name means “Demigoddess of Bane”.||Daraus ergibt sich, wenn in der englischen Sprache beim Namen Semjase das E am Ende mit I gesprochen wird, so also Semjasi, der Name ‹Halbgöttin des Fluches›.|
|Such false names and unworthy concepts respectively are unworthy of our languages and dialects, even if only a single letter in the word itself is wrong and is pronounced differently than the written form.||Solche falsche Namens- und Begriffsunwerte resp. Unwerte ergeben sich in unseren Sprachen und deren Dialekten auch, wenn auch nur ein einzelner Buchstabe im Wort selbst falsch und also anders ausgesprochen wird, als dieser in der geschriebenen Form gegeben ist.|

Semjase is a widow, she was married for seven years, but tragically lost her husband in an accident. Approximately 200 years ago at about 130 years of age, her spouse had been participating in a research expedition in a foreign galaxy, at a time when a certain hyperspace technology was relatively new to them. Of the two research ships dispatched for this particular task, only one returned home after eleven years, unfortunately the other with her husband aboard, suffered some form damage to the control system and crashed into the star of that system. Her marriage was without children.
On the 15th of December, 1977, she suffered a life-threatening accident at the Semjase Silver Star Center itself (which is named after her), in Hinterschmidrüti, Switzerland. She had to be taken back to her home planet of Erra for immediate A&E medical treatment with subsequent rehabilitation. Part of her brain was damaged in the accident, because by Earth standards she had clinically died, which took some time to repair and by the assistance of the individuals in the wider Plejaren Federation. Were she an Earth citizen she likely would have remained dead because of the incident or at best been disabled by it. However, this type of personal injury and death would not have occurred or even been possible if she was an Earth citizen to contrast, because it was related to a supporting technology the Plejaren use while they visit other worlds.
In May 1978, she returned to Earth and resumed her regular communication with Eduard until 26th March, 1981.
From March 1981 until the end of January 1984, she was again absent because there were other duties she had to fulfil on other worlds.
On the 3rd of February, 1984, the last conversation took place between Semjase and Billy. As an after effect of her accident on the 15th of December, 1977, she suffered a cerebral collapse in the beginning of November 1984 and was transported again as quickly as possible to the DAL Universe where she was healed by the help of Asket and friends the Sonaer. Her father, Ptaah, explained that the complete regeneration of her brain and all psi-powers, (sensitive) abilities and memories, lost during her collapse would take about seventy years. During this time Semjase will spend most of it in the DAL Universe.
She disagrees with Earth religions and knows the truth due to education.
She disagrees with Earth politics and thinks that we would be better off without it, however she knows the truth due to education and is forbidden from interfering in Earth affairs by Plejaren Federation law. 
Please take the time to allow for the awareness that there is such a massive quantity of information on each of these main Plejaren personnel in the original FIGU documents; we could paint any picture we wanted of each and any of them by either including or not including, omitting, whatever we wanted about them. By leaving out key critical details and focusing on the qualities we wanted to show the reader, just like a journalist does frequently I suppose you could say. Future of Mankind doesn't do that, at least not deliberately, we try and be as neutral as possible. This web page about Semjase is not an exhaustive account, it's been built up and accumulated here on this page from the original documents by many voluntary contributors, over some time and it's written in summary of a number of sources in FIGU literature, see Contact Reports, and Books. It's a bonus page which is not an official FIGU publication and the assumption is that readers have read those original FIGU publication documents already before this page.
There are numerous websites out there (which don't interest us whatsoever) which use the 'Semjase' name and write whatever story they want or imagine. We only use documents produced by Billy Meier and FIGU. Due to this situation and it being a popular page, editors are encouraged to reference everything written on this particular page, and rewrite everything so that it's as close to the original documents as possible. We tend to endeavour to reference everything on all Meier Encyclopedia pages, but it's especially important on this page, because of all those false accounts of Semjase all over the internet, thank you.
