I love corrections, don't you?Eldritch Warlord said:Offensive Bias was actually in charge of a fleet meant to kill the Gravemind (or at least hurt him and make all the other Flood stop their expansion and go protect him). And I don't think there's any explanation ever given as to why the Forerunners didn't rebuild out of the Shield Worlds after the Halo Array was fired (maybe they were all abandoned when the Forerunners made the Maginot Line and never were used to keep attention away from the Halos, maybe the shield worlds simply didn't work). Also the Flood on 05 seem to have broken out on their own thanks to Penitent Tangent's lax containment protocols.
Stargate's Great Alliance might have been able to do as the Forerunners did. The Ancients did build that Dakara Superweapon.
First off, his name was Mendicant Bias, not Offensive Bias. Second, he was not in charge of a fleet meant to kill the Gravemind, his objective was to study the Flood in an attempt to find an exploitable weakness. In his study of the Flood, he became fascinated with them. He saw how resilient and how perfect they were in comparison to his own makers, the Forerunners (who were just Humans). He was also in charge of the shield worlds and the Gravemind saw and exploited this. The Gravemind convinced Mendicant Bias that the Flood truly was the ultimate race and that his makers, the Forerunners, were just trying to halt progress. He convinced Mendicant that they were just an obstacle in the way of true perfection. The Gravemind also promised Mendicant Bias all the knowledge he possessed, which was all the knowledge the Flood had accumulated since the first Gravemind, should he betray his makers. And so that is exactly what he did. Mendicant Bias betrayed the Forerunners for the Gravemind and shut the portals to the shield worlds. By the time he came to regret his decision to betray his former masters, it was too late.
