We also learned that:

- There was another Gravemind before the one stopped by the Forerunners and the modern one which is on the High Charity.
Quote:
It spoke to us
{/MOCKINGLY, DISMISSIVELY/}
It has done this before
{/ELSEWHERE/}

- The Forerunners wanted to obliterate the antithesis of life: death (or the personification of death and darkness, the Flood).
Quote:
KNOW THAT ENERGETIC AND TENACIOUS AS LIFE IS
IT HAS AN ANTITHESIS JUST AS POWERFUL
IT IS THAT THING THAT WE MUST OBLITERATE

- The Forerunners created or found a rival, contender, to fight the flood.
Quote:
I pray that it doesn't come to that.
{/I PRAY THAT THE CONTENDER SUCCEEDS WHERE OTHERS HAVE FAILED/}

- The title reclaimer refers to the one who will come to reclaim the Ark and revive the species which were destroyed by the Halo's firing and not just one who will reclaim their technology.
Quote:
The thing we built on that world will vouchsafe their lives,
{/But perhaps one day it will be used for its intended purpose./}
If the plan succeeds, and they are saved, it will be a good world.
If the plan fails,
{/And the adversary succeeeds./}
it will remain an enigma forever
{/With no-one left to reclaim it./}
The thing= The Ark= The thing

What do you think?

Not sure if you have made it into the Speculation forum recently (and I hate to do a shameless plug of my own topics), but I did a kind of (or "NAR" as we have so lovingly dubbed him) and tried to stick to facts as much as possible. I posted it in Speculation due to the implications of some of my hypotheses. Anyhow, check it out -- I know it's long, but it needed to be, in order to be called "Comprehensive" (which is pretty much a four syllable word for "long").

Wow great analysis!!!
However my intel was to report what we've learned throughout the Iris campaign.
Do you think NAR has anything to do with Cepheus from those fake halo 3 script papers?
