The original loot cave in Destiny is dead, but its spirit lives on. In fact... it may be haunted.
As part of the latest update in Destiny, Bungie has added a bunch of hidden remains to the Loot Cave in Skywatch. When you disturb them, the following takes place:
"A million deaths are not enough for Master Rahool."
Here is the original video. Master Rahool refers of course to the Cryptarch in the Tower, who decoded the countless engrams farmed from dead enemies on this spot. Apparently he's still not satisfied, which seems pretty typical of him, if you ask me.
