Inscrutable, yes, but this is exactly the sort've thing that we used to get in droves! The H3 terminals were cryptic enough that the detail was lost even if the story was there. This, however, is so vague it must be intentional - and so good job 343. The wonder of the original Halo was having clues but nothing else to go on, and that's what makes for good discussion :)

The log about the Warden is almost troubling; I'd not made the connection between him and the Domain but now you mention it it seems most logical. Assuming the Gravemind didn't lie to the Librarian 100,000 years ago, then the Warden had no reason to exist until the Domain was reactivated. But, reactivated by what? I can't escape the notion that perhaps the Domain is tied to the existence and resurgence of the Flood....
