[quote]Ok, so the Domain was a precursor construct which means that there was some organic matter used in the making of it. So when the Halos were fired the Domain along with the star roads were destroyed right?[/quote]Halo's don't destroy organic material, they destroy neural pathways of sufficient complexity. For Precursor constructs, they are made of neural physics. Which is why they were all destroyed by the Halo pulse. So, no, the Domain did not survive.
