: Well, been a Halo fan for about 10 years, played all the games several times,
: have read most of the books(most importantly just finished the Forerunner
: saga)... I still don't understand, really, how the Flood survives into the
: present(future I guess - 2552). Cortana claims Halo doesn't kill them, it
: kills their food. Silentium seems to suggest they do kill the Flood(along
: with almost all other life). Why is there still Flood on the
: installations? Are they safe havens, like shield worlds? I know they're
: referred to as Fortress Worlds at some point. Did the Forerunner really
: think it was a good idea to keep samples around after how much of their
: civilization was destroyed? Perhaps unwilling to commit genocide? The
: creation of the rings seems to strongly suggest otherwise... I know they
: do reseed the galaxy with many species though. Why is there a Gravemind on
: Installation 05?
The Flood have been loose on Delta Halo for almost 100,000 years, there is no telling whats happened in that time. Maybe other mystery ships landed like in the Anniversary terminal? Maybe there were Indexed species accidentally left on the Halo after or something. I have a feeling 343 has a plan to address this...hopefully in H2A terminals.
