The Arcturians are compassionate and benevolent beings that are assisting humanity during the Ascension Cycle in accordance to the Guardian Host Law of One protocols, they are the closest example of our future humanoid family that has undergone a 5D ascension process, that is similar to the planet earth's current Ascension process. Arcturus is the brightest star in the constellation of Bootes.
The 7D Phantom Wormhole has caused problems for the Arcturians because it is used by the NAA, and leads directly into their system. The conflict in this phantom wormhole is primarily with the Draconians, and thus they have helped to thwart many of the Zeta Drakonian Agendas from impacting the earth surface. As a result, they assist us in protecting and repairing the 7D Violet Ray, magnetosphere and rehabilitation of the planetary gridwork that is directly impacted by the phantom wormhole issues and the 7D Crucifixion Implants. Hence, they can also be considered the 7D plane gatekeepers, or Guardians of the 7th dimensional plane.
Personal Experience with Arcturians
In 2002 a Christed ET Group, called the Arcturians took me on their Lightship and showed me a Beautiful Color Holographic Image of my body being repatterned and rewoven through its multidimensional layers. I knew it had something to do with DNA activation but I still had no idea what all of that meant to human consciousness. It was a very sweet experience and I remember we all were laughing a lot. Later I found out they were showing me my future destiny in working with the QXCI body scanning technology and I did not yet realize it. Right after this event, I was introduced to the QXCI by several sources and realized it would have a part to play in my divine purpose. I was still making a living as a Tax Accountant, so I had no idea what mountains spirit would move in order to set me up as a biofeedback practitioner for the workign with the Quantum Biofeedback Scanning Device. I am convinced it was the Arcturians that helped to bring this technology to the earth to help humanity heal their DNA. 
Starseed Session Transcript - So as the earth was the experiment here you are on the earth, you are in the laboratory, you're working with the genetics that are being held in your own body, that you are experiencing yourself as on the earth. While simultaneously in your spiritual body the life form of let's say the Arcturians are being healed by what you're doing down here, so the future ramification of their experience is not impacted by the problems we have on the earth in the lower density. This is really hard to explain I hope it's understandable.
Because it's like being an inter-dimensional portal and realizing we are the sum total of everything. We are the Arcturians, we are the Sirians, we are the Pleiadians, we are connected to everybody in this divine angelic human form as we are. And because of that we have an unusual consciousness power that allows us to be an inter-dimensional portal at every single axis point and vantage point that exists in this universal time matrix structure. And those levels of consciousness actually do not have the same access level. They have their level of consciousness and vantage point, from where they are stationed in the time and space field, but they are not in the same level of physicality we are.
Because we are at the densest and lowest point of the universal matrix, it is like we can open a light tower from here on earth all the way up through the higher vibrating realms, where a lot of these other systems exist. And they can't do that from where they are positioned in the field. So it's like all of it is happening here on the earth, believe it or not. All of it, everything that is impacting every single life form, planet that has existed in our universal structure is a part of us is us. Just like when we talk about the extra-terrestrials, these are other aspects of us that we have come to basically heal ourselves at that level of identity.
As Starseeds, many of us have come to heal the Sirians, we've come to heal the Arcturians, we've come to heal all of the Universal DNA, because every single one is here on earth during the Ascension Cycle. Every single piece of Arcturus, those form Orion, such as the praying mantises, all of these extra-dimensional beings, a piece of them, their DNA and consciousness aspect is here. Which means actually the whole of them is here. That means that once we heal the planet if we can ascend the planet, if we can succeed at the certain levels of this genetic experiment that we endeavor to, it's like it ripples beyond this earth and beyond what we can imagine in terms of the greater good for all.
Arcturian 7D Phantom Wormhole
While capturing souls, capturing animals, capturing nature, whatever levels of capture, that would mirror an exact replica of the item, person, or animal in a holographic projection into another phantom dimension. This phantom dimension feedline, influences 7D phantom Arcturian intersections, as well as 7D logos and planetary brain controls. This soul capture creates a probable future timeline of that person or animal here on 3D earth now, as its replica parallel clone is leading it towards its own pathway of destruction, into a phantom dimension of enslavement and eventual consumption by these negatives, in controlled artificial future timelines. This is exactly like understanding the computer technology of a mirror site server. When one wants to have multiple copies or clones of the same website content accessible in many countries, they will create a duplicate of the original site and replicate its projection onto many internet IP addresses, or vector locations in time and space. This soul capture technology was doing exactly that. 
Rod and Staff Planetary Architecture
To support the change in the Gender Fin rate of spin and to help correct the male and female rod and staff planetary architecture, Starseeds have been processing 6D-7D wing trauma that connects into Sirius B and Arcturian energies, as well as the Gaian timelines recorded in the Indigo and Violet Ray spectrum. Wing Trauma is directly connected to the Michael-Mary Reversal networks and the alien machinery placed in the planetary grids that split gender apart, which are anti-hierogamic technology. The result of this grid is to promote the splitting apart of the layers of sacred marriage that occur at the 6th and 7th dimensions, through the corruption of the Indigo and Violet Ray, which is the spiritual ascension process of Building Wings. The process of building wings through the 6D-7D horizontal intersection is revealed to be critical for correcting the planetary Horizontal Rod Pillar for the masculine principle.
Epsilon Sequence Tool
Transcript - We now begin technique two which is called the Epsilon Sequence. This came to me during a time when the Arcturians were very present with me. At that time they were showing me how to interface with the QXCI or Quantum technology. The Arcturians are very technical and have some very advanced healing technology. For a time they were showing me how consciousness can interface and influence holographic patterns. They were showing me how the holographic patterns, blueprints in the DNA, can be influenced through consciousness, giving a feel for how to work directly with the DNA for corrections. And this technique came out of that time period. It is an Arcturian tool to seal the Soul body, solar body, which can be really helpful at a certain stage of development. See Epsilon Sequence.
