: My own guess is that the Chief has advance warning, possibly due to the
: Librarian activating the genetic fiddling in his genome, and is trying
: either to stop them activating or to evacuate the area, save as many
: people from being killed as possible. ONI has misinterpreted his movements
: to be him deliberately activating them, either to use against the UNSC or
: against some other enemy with the casualties as collateral damage.

: As for what the Guardians could be...I don't know. Why are they only waking
: up now, when some of them were on planets like Meridian that were glassed
: by the Covenant, who should have registered their existence with
: Luminaries? What do they want, what were they build for? No clue. I
: wondered at first whether they might be something to do with the
: Precursors, either Precursor technology or something the Forerunners built
: to counter them, but that was mostly in response to early rumours that the
: Flood and Precursors would be separate enemy factions in the game (a
: rumour I now highly doubt.) My guess is that we won't find out everything
: in Halo 5, but that it will be the new ongoing enigmatic
: technology/faction to be unravelled across the series of games 343i want
: to make - like how we didn't know everything about the Halos in the first
: game, but found out more over CE, 2 and 3. Maybe the Chief has no idea
: what they really are ether?

Seems like it'd be a good idea to not have your Luminaries able to identify *every* piece of tech. The Guardians might fall into a sort of "classified" bucket.
