The whole thing is basically the engineer version of a nuke, rendering planets permanently hostile to other life forms and destroying civilizations by transporting the weapon inside its members - and thus following trade-routes.

I still have to watch the prequels after "Prometheus", but that prequel was one of my favorites in the series, and your comment makes me want to go watch them.
Regarding cannon vs canon, the way I remember it is that "you need a double-n for a cannon to be double-barrelled." I have no idea whether that's useful to anyone else.
Etymologically, they are both related to "cane", so it's pretty much a historical accident that we now spell them differently to each other, or that it's not the other way around.
It differs a bit in intent though: Its eldritch designers seem to have intended it as a high-reliability remote construction drone.
