These are extradimensional beings that have lost their Consciousness connection to god source and are utilizing human and other beings as their food source (like a parasite) to live thousands of years. They do not have emotions as humans have but are highly intelligent as they are working on higher mind principles than the human Three Layers of Ego. They are similar to a Mad Scientist that manipulates and genetically modify human beings, similarly as a farmer interested in gaining more resources out of his herd of cattle on the farm. Many of them are inherently violent. They consider humans an investment in their energy resource portfolio. The NAA or Archons can be best understood as a Psychopathic personality or identity profile with a Lack of Empathy that has no feelings of remorse and no caring towards human beings. They regard human beings as inferior, stupid and many times use forms of mockery to create intentional harm and violence for their own amusement.
These beings have been manipulating the human world of affairs for thousands and thousands of years, since the Atlantian Cataclysm for their own purposes. See the Ages of Humanity. These are inter-dimensional and extra dimensional beings known as Fallen Angelic in ancient history and they use many technological manipulation methods to Mind Control and negatively manipulate the future direction of the human race. Once such negative manipulation is installing the Armageddon Software into the planetary brain in order to install False Father Negative Alien Religions based on serving the Yahweh and JehovianAnnunaki Collectives. See Dark Force Manipulation Methods and Mind Control.
There are many types of these extradimensional groups and races. Some have lab engineered bodies, some are capable to project their Consciousness throughout time and space without a form body. TheNAA is a term used which includes Negative Aliens factions which include Annunaki, those in the Black Sun Program the Alpha Draconis/Orion Group, Greys, Zeta, Thoth Group, Drakonians also called Reptilians etc.
Whoever controls the Mind controls the body, mind and Soul. Alien Implants are used to Mind Control the masses to form socially acceptable belief systems and shape anti-human value systems which are used to condition humanity to accept spiritual abuse from the Negative Aliens and to self enforce their thought systems of hierarchical enslavement and fear. This is a divide and conquer strategy of the planet and humanity. The Power Elite are the small group of humans that share similar bloodlines that represent the NAA. These humans are ensured they remain in power on earth with materialism and military weapons as long as the enforce and feed the Archontic Deception Strategy.
Hidden ET and Fallen Angelic History
Now during the Atlantean cataclysm and what is known as the Luciferian Rebellion about 26,000-30,000 years ago, this is when the planetary star gates, the planetary grids Ley Lines became controlled by theNAA Controlling races such as the Reptilians, the Annunaki , the Alpha Draconis/Orion Group Draconians. And this Golden Eagle Grid grid became, during this time, under the control of these beings who used these collective consciousness grids for reversed purposes of malintent designed for the NAA and the False Gods which was the opposite from their original purpose.So, in the last 26,000 years, the Golden Eagle Grid became controlled and was primarily used as a mind control broadcast station, literally, that would send out false information or manipulated information to the mass human population. One purpose in the Iran Gate is to send out False King of Tyranny patriarchal domination mind control through the ArchAngel Michael Matrix collective. It was sending out information that was about the program that the Annunaki to continue to plummet humanity into false Timelines of which is one of darkness, enslavement and separation using software called the Armageddon Software, Metatronic Reversal and Victim-Victimizer. The Golden Eagle Grid literally became like a mind control weapon because that is what they have been using it for. It had been reclaimed back a few years ago in terms of the Guardian Founder Races who are working to rehabilitate the places of the fallen consciousness grids Fallen Angelic mind matrix and override the patriarchal mind control through the Solomon Shield and activation of the Mother Arc Hubs. See Ages of Humanity.
The War Over God
The Fallen Ones started to infect their diseased minds with the Mental Laws they created as falsely masked Universal Truths. To make this actualized in physical they cultivated their human and non-human contacts into alliances that would serve these agendas. The Fallen Ones infected the God-King lineages of the planet and replaced beliefs of sovereignty and freedom as Universal Truth to concepts of Hierarchical Enslavement, genetic discrimination and karmic retribution. As they proclaimed and defended themselves as the True God Creator, the War over God and God’s Natural Laws became the main power conflict in our system. These False Gods in their corrupt actions to have dominion and control over others imprinted the Mental Laws with the dark archetype of the False Gods- False King of Tyranny. These Fallen Ones (Fallen Angelic races] are the consortium of Negative Aliens promoting their human enslavement and control agenda NAA on earth, as well as the Imposter Spirit forces that make up bothSatanic force and Luciferian forces.
When our Planetary Logos was invaded and corrupted by the Reptilian Controllers (Archons) of the NAA, the planet and our race were impacted dramatically. It meant we were no longer free to create and evolve as per the original Blueprint of our intended creation, and we had no memory of what had happened to us. We were recycled through continual reincarnation into the Astral Plane with no memory of the past lives, who we really are, where we are going, or what our real relationship is to God and what humanities “purpose” actually is. Over time most of us lost our feeling connection to our Soul Matrix and we became numb to the pain in order to survive in anti-human based structures. What has happened to our planet is not human, it is “alien” to the true nature of humanity.
To be able to understand the sociopathic sick mind of Archontic Deception systems, one would need to better understand the general attitude of an AD infected human or nonhuman (NAA) as having little to no remorse or empathy. If a technologically advanced extradimensional race has decided to implement a gradual takeover of a planet and its inhabitants, what kind of strategy would it use? First they would look to how they could maximize the efficiency of the invasion process and reduce the expenditure of resources that they have to generate themselves.To achieve this goal the secretive infiltration of the core societal organizational structures such as: religions, medical, financial and legal systems, would be ideal to shape the value systems that generate reality belief systems they want to control. Through the engineering of a labyrinth of self–enforced enslavement policies based on fear and intimidation among the earth inhabitants, they would achieve the use of minimal “off planet” resources by piggy backing on the earth-human resources. The people on earth would effectively enforce their own enslavement as well as enslave their own global human family by giving up their rights and their resources. This is very effective for takeover and invasion with minimal resistance or revolt by inhabitants who are unaware they are being invaded. This is called the Archontic Deception Strategy. 
According to remote session intelligence collected and Guardian mentorship, Aleister Crowley is a key figure in cooperating with the NAA, starting from Grey Alien contact made in Cairo, Egypt in April 1904. They scribed and implanted him with "Book of the Law" which is the central sacred text of Thelema, written down from dictation mostly by Aleister Crowley, although his wife, Rose Edith Crowley and the entities themselves are known to have written phrases into the manuscript of the Book after its dictation.
This Negative Aliens contact began a lifelong series of interactions and collaboration with NAA to bring into physical manifestation Satanic forces of the Black Sun Program under the guise of representing themselves as "Holy Guardian Angels". They collaborated with Crowley, sent him to various key locations of the earths power vortexes to open closed portals and assist in their patriarchal domination hijack of power grids of the earth.
Negative Alien Religions
One of the largest lies promoted to divide our race is the War over Gods promoted through Religious Violence. The false archetypal story of a Crucified Christ figure is a mockery to further enslave humans into believing in a salvation model through a Crucified Christ. It represents the tortured human being, as we are all the Christ, and we have been crucified/implanted as our planet was invaded. These structures are called Crucifixion implants. These Crucifixion Implants are tangible control structures placed in the 7th dimensional logos, and therefore it is in our individual bodies, in the 7th dimensional chakra, its complex, meridians, and the entire left side (our female spirit) of our bodies. We are not aware of these implants until we open the 7th Chakra Seal and start connecting this part of our 7th layer Lightbody to our personal consciousness field.
