In the deleted scenes on the Collector's Edition DVD, Joseph Staten describes and shows some of the Covenant's history. Specifically, he displays a pre-render of the Covenant Murals. “We have this fantastic story arc that we're trying to get across and we have all this back story that we're trying to get across. And there comes a point where we look at the amount of time we have left to finish this game and we realize that we're just crazy and we're not going to be able to do all of this. So we pick our battles with what we can cut out...” — CJ Cowan
