Anunakene

They come from planet Nibirue (aka Nibiru). Their planet is part of the same solar system as Earth, but with a much longer orbit...it comes closer to the Sun every 4.000 years, and not every 3.500 years as commonly accepted.

They resemble Humans but are higher (2.5 meters/8') and more muscular. When they first visited Earth there were already other races established here...some malevolent and with supernatural powers. The Anunakene defeated them and became the most powerful race on Earth.

They genetically engineered the most intelligent non-alien beings on Earth (us...at the time not much more than smart primates) in order to have a race of slaves at their disposal. At the time Samael amd Lilith were the Anunakene King and Queen.

They were not aware of the presence of Reptilians on Earth.

They only cooperate with one other race: the Zeta Reticulai. Not to be confused with the Solipsi Rai (aka "grays").

Eventually they left Earth (unknown reasons) but before they left they created a sub-species of the Zeta...this species eventually became rulers of Egypt (Pharaohs) until the Reptilians infiltrated them (as Temple Priests) and ended their Reign.

They gave birth to the legends about "giants".

They will return one day as promised by themselves, however the date of their return is still a mystery.

They do know all that is happening on Earth as well as in other planets where they had influence (and/or still have).

The proximity of planet Nibirue (aka Nibiru) does cause cosmic instability and weather-related repercussions in all planets of our solar system, but does not cause the amount of destruction that it is usually accepted and believed.

How far they are it is still a mystery.
