I was at the Skywatch, working on bounties, and I found something pretty cool in the old loot cave. In the Cave there is a pile of remains, and you have the option to disturb the remains. When I did this it the game played an audio message that said, "A million deaths are not enough, for Master Rahool." I believe this is a joke referencing this as the first loot cave and when you may have gotten a legendary engram after hours of farming(and a lot of killing) you would still get a pretty low quality item from the Cryptarch, Master Rahool. I doubt I'm the first one to find this, I just found it worth sharing.
