Covenant murals

Covenant Murals after the 3:00min mark In the deleted scenes on the Halo 2: Collectors Edition DVD, Joseph Staten describes and shows some of the Covenant's history. Specifically, he displays a pre-render cinematic 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

The seven murals show the seven "ages" of Covenant history. There are a number of scenes that were cut from the game that show some murals that depict the Covenant's history.

Se7en has created re-renders of them on the Bungie forums, and Bungie acknowledges them as correct, you may view them here: http://nikon.bungie.org/misc/hallofmurals.html

Trivia
There are seven murals, this is probably yet another one of Bungie's seven references.
