[quote][b]Posted by:[/b] Nocbl2 I think we should all recall that the Didact and Chakas were both at Installation 03, along with the Composer. Would it be that surprising for the information of Requiem to be stored with other relevant materials and data, and/or the Forerunners leaving behind something from a blown up ship?[/quote] You mean in Primordium, right? I thought that was Installation 07? Also, both halves of FuD made it through the portal. It's just that only the front half made it to Earth. Requiem isn't necessarily close to the Ark. Remember, that a Halo was activated. They were far enough away to not be killed. And they drifted for 4 years form wherever the portal dropped them off.
