I noticed that many readers were confused by the Martian infighting and the conclusion of Quadrant's personal arc, so since I couldn't sleep, I decided to write an analysis.
P.S. This part of the plot was limited by length and couldn't be written in much detail. It was only meant to explain the endings of Quadrant and the Mechanicus, and resolve the Kelbo Hal crisis.

If this book had been called Quadrant's Cultivation Manual, this section alone could have been expanded into a hundred-odd chapters, because the oil boys' infighting was genuinely fascinating.
Anyway, here's how it went.
The broader background of the Mars incident:
The Horus Heresy never happened, so Kelbo Hal could not possibly receive support from the rebel faction.

That was why the Emperor had Cor show Quadrant the truth about the Mechanicus.
The truth about the Mechanicus inside the chip was not actually the truth either. It only existed to make Quadrant willingly
