What the Alchemist means, I think is, when prophesies are made, for instance about the Ascension, then myths and narratives are called into life, with the purpose of becoming useful to a certain political direction at the time of the prophecy (for instance the Ascension). As an example, the bloodlines of Nimrod (Secret World Government/Illuminati) would be interested in being able to demonize the main players in the Ascension movement. Now take a look at Revelation 12:9 and know that my birthday is on the 12th of September. Coincidence? Revelation 12:9, King James Bible:
And the great dragon was cast out, that old serpent, called the Devil, and Satan, which deceiveth the whole world: he was cast out into the earth, and his angels were cast out with him.
Who are "his angels"? The lightworkers?
"Cast out", if anything, suggest that not everybody understands the concept of the descending being (see Glossary), who travels (in whatever way) to lower dimensions in order to learn and evolve or simply to help (mostly a combination). They aren't cast out. They "fall into experience" as is said, but the fallen angels are actually the Orion reptoids, those who have lost their connection with God. May God keep their divine sparks safe and help them find the light. And may He and them forgive me, as I have forgiven them. If you think I deceiveth the whole world, then you're still welcome, but you may want to stop reading now.

There is nothing to add, nothing to gain, nothing to seek.
You do not need to strive, to beg or to pray for things. For I already know what you need.I, the I that you are, am already complete, whole and perfect. Rest in the awareness that I and the Father are one. That I am within you.

If you would dig through the Vatican's cemetery, you'd find plenty of these. A miter would look just dandy on this guy.
Speaking of Ms Elyra, she has an indepth knowledge of the shadow world which you normally expect from whistleblowers or ex-insiders. I'm not going to speculate on her specific situation, but it seems in order to elaborate a little on such people and their position in the ascending world of today. I have noticed that many whistleblowers are concerned, if not downright afraid about their perception and reception by society.
Here I'd like to note that lightworkers are not here to preach to the choir, to convince those that need no convincing, but to reach out into the dark and retrieve those who are willing to step into the light, and in the final stage of the ascension process one of our priorites is the integration of all awakened souls, not just those that were alseep, but also those that came out of the dark.The Book of Revelations never prophesized future events, it simply described Atlantis' final catastrophic days, transforming your most traumatic genetic memory into anticipated divine punishment.
I have some doubts about "Seraphine" being of the light, let alone the Galactic Federation. Indeed, her messages contain 80% truth, which I will take with gratitude. As always, take what resonates and leave the rest. I included the above snippet to illustrate that religion is neither divine nor man-made, but exopolitical.
