I was looking over some of my old beta footage and I noticed something I hadn't before. This picture is of the back wall inside of the hangar bar area. On this wall are a bunch of "trophies". Things like Cabal shields, Vex guns, Vex chest pieces, and what have you. Clearly this wall's theme is [i]the wall of things guardians have killed[/i]. But what is [b]that[/b] on the wall? That's no cabal skull, not hive either. That my fellow guardians, might be the skull of a dragon. 9/9 needs to hurry up.
