I speculate that the abominable intelligence in question is the Kaban Machine.

Its demise was after all never fully confirmed.
SPOILER
I finished reading it a couple of weeks ago. It wasn't bad. At first I was afraid (although I am Kharn and as such never know fear as you humans do) that we would be given another tedious rehash of the rebellion on Mars. By the wrath of Angron we were spared such dross. The author wisely decided to skip it and get right into some good old killing. The concept was set up well and the players did their part. The ending was actually satisfying for me. But then, I do like such endings to stories. I don't wish to spoil anything for anyone else, but things die and a story of interest occurs.
The author, however. Ended far too many of his sentences with however. It became very distracting, however. To see a couple of sentences on a single page, in very close proximity to one another, end with the word, however. Especially since a similar thing had happened a couple of pages before that, however. And you then become aware that this has occurred a few times before even that, however.
When one notices a writing technique like that it's either not working or has been used a little too often.
In this case, it worked just fine, but popped up too often in a short space.
Anyway, it was not enough of an issue for me to hunt him down and gut him. The author, Lord Sanders, shall be allowed to live for now.
The most important aspect of this novel is that it has set us up for great things to come. I shall be waiting eagerly.
