You're not supposed to even touch the material in Liber Falxifer III until you've had significant time with an ensouled Qayin statue, according to N.A.A. 218, so if you were actually an outer representative, you wouldn't be suggesting such a thing so easily. Additionally, the Black in Green has been mentioned since Liber Falxifer II, though there are vestiges of that particular Qayinic path in Liber Falxifer I for those who are paying attention.
With that being said, what's your angle here?
Found the forum on the internet; currently do a lot of "explaining the basics about the systems presented in the 218/182 books" in different online discussions (mostly 4chan) while waiting for a bunch of "World Progress" to kick in; so figured i'd check on here as well if there's any 218/182 related subjects to pitch in additional guidance in.
"you wouldn't be suggesting such a thing so easily"
Why not? Know very well how the Cross Stations of Nod work; am part of the more advanced "full-time walkers of said path"; very advanced experience with LF3's Cross Station system.
If you want to you can in reality "start working directly with the LF3 path as a newcomer, and fill in with things presented in previous books as you're working with LF3's Step by Step system"; Liber Falxifer 3 was designed as a "Step by Step from novice to expert/master" system, introducing you to subjects like for example "The Spiritual Alchemy" (the supernatural Geneology upgrades the Qayinite path teaches) step by step.
The Sigils of the 218/182 books are "meant to be experimented with; ie Decyphered by experimenting with them until they start making sense".
Overall for direct comprehension of "how to walk the path properly"; seek direct communication with Q and the general guiding familiar spirits of the path through "asking the guiding spirits in the books directly"; fully approachable by "general use of the books". The books themselves teaches you stuff when you're looking for direct guidance.
Also usually reccomend "different media to study for deeper comprehension of the path"; for example a lot of the 218/182 systems mechanics are presented in different videogames (video games being heavily "Black in Green developed btw; a majority "isn't manually created by hand, but rather spiritually generated"; like a vast majority of TV-content as well; "conceptually generated entertainment media");
for example "Path of Exile" (the games name being an obvious indicator for those keeping track for Qayinite symbolism to tag along with) is highly relevant to study from the point of view of "Book of Sitra Achra/Liber Falxifer praxis".
If you've played said game, study correlations in the Emissaries of Thaumiel; compared to information you've been presented with in the gameplay mechanics of said game. Overall work a lot with systems like the Emissaries in Book of Sitra Achra; and look for "correlations to things you have learned elsewhere; information that has been conveyed in other places"
"Grim Dawn" being another "reccomended game for those with a "current 218/182" interest; also heavily educational on spiritual metaphysics.
The "Diablo 2 Genre" games being one of Qayins favourite genres; something he has been spiritually heavily involved in to begin with (you can sense "Q" as heavily spiritually involved in for example Diablo 2; in the entire general aesthetical vibe and all).
"RNG mechanics" like "randomly generated area layouts and RNG loot generation logic" overall which is heavily present in said genre of games is very relevant subjects to recognize in order to understand Qliphothic stuff better.
"Rogue-like" games are very Qliphothic in essence.
