Much like stories regarding gods and such in other games, and much of what's posted in Shadowland/Jackpoint comments, you have to take the story with a grain of salt. It's been a while since I last read Clockwork Asylum, but I think I recall most of it being "as XXXX tells it" type of story.
The version of the story I gave is the one Roxborough gives to Alice near the end of the book, when begging for his life. Before that, there are several other versions given by Roxborough and Alice. You can sum them up to two different stories, one with Acquisitech/Roxborough responsible, the other with Dunkelzahn/Gossamer Threads.
The only hard fact, as far as book goes, is that Damien Knight was David Gavilan and worked at Acquisition Technologies (with Lucien Cross) at some point. That piece of information is in
Blood in the boardroom Game Information, page 57.
Even with the whole unreliable narator and stuff
I'm pretty convinced Jak Koke and Mike Mulvihill intended it to be the actual truth.
