[quote][b]Posted by:[/b] HipiO7 Alright, that we know. But [i]how[/i] did the outbreak occur?[/quote]How the outbreak within the [i]Sentinel Wall[/i] occured I do not know, haven't found any clues on that whatsoever, but what if the Gravemind is the same Gravemind that spoke to MB, the one present during the war, he might not have started out on Installation 05. To quote Cortana:[quote]"This lake couldn't have been created by volcanic action, which means it was either built this way on purpose, or was created by some other cataclysmic event. Sorry... were you trying to kill something?"[/quote]And what do we find beneath the lake? But then they covered it up; rebuildt structures here and there:[quote]"You know, I think the Forerunners built these new structures around the old, to protect them, to honor them. Pure speculation, mind you. I'd need to make a thorough survey to be sure."[/quote]Did the captured 2401 order the sentinls to rebuild? (The Graveming is after all able to teleport John and Thel to various destinations on the ring, something I doubt he would have been able to do before he somehow got a hold of 2401, so he does have some kind of control). Pure speculation, mind you... [Edited on 10.04.2012 5:16 PM PDT]
