I get where you're coming from. Interesting theory, but the prefix "lupi" as in lupine means wolf. Crest of Alpha Lupi would mean Crest of the First Wolf. Alpha is used as a term for the lead wolf in a pack. So the armor belongs to whomever that was. However, note that the game frequents references to wolves, such as in crucible with Strength of the Pack and so forth. One of these occur when you are in first place if I'm not mistaken. So in essence, this could also mean something to the relation of just being the best or in first place, and here is the armor of the first place holder. Its possible that one of the Brays were just legendary in Crucible, more specifically Ana Bray. Or the armor was made in her honor for Twilight Gap, maybe she killed the most enemies. This would also explain the "Dreams of Alpha Lupi" because everyone dreams of being first or the best and in reality, at some points in anything you do on Destiny, you are. I.E.- First Place at the time in a Crucible match, Most Kills at the end of a strike. That's more than likely why it says "you are the Wolf"....Because you are. The titan version refers to this probably because if we are all wolves and/or part of a pack, the "consent" would be dying to you (Crucible) or allowing you to die and not backing you up (PVE) and vice-versa As for the Brays, I believe they have an entire story in their own and they were probably part of the main story background before it became fragmented and almost nonexistent.
