Can someone explain to me the difference between the greater and lesser arks? When I red the wiki it seemed really diluted and non-concrete info. I.e: Which one is installation 00? What was the battle between gamma halo and the greater ark? We're there "larger" halo rings? What's the difference between the two? Is the lesser ark 00? Also: how close is Requiem to the Ark? I'd imagine it would be pretty close but I wouldn't be too surprised if it wasn't considering Forward unto Dawn was drifting through space for quite a while.
