It appears that with today's update to Destiny, Bungie left a special little message for Guardians who felt the need to return to the original loot cave in Skywatch on Earth.
Discovered and shared by YouTuber Jonty Alphaville, the loot cave now has a pile of charred bones with an option to "disturb the remains." Here's what happens when you do so.
For those having a hard time understanding what's being said, it's: "A million deaths are not enough for Master Rahool."
Master Rahool, of course, is the Cryptarch in the Tower who identifies your Engrams. It's a cheeky response to the cave exploit which was used by many players to farm for Legendary Engrams when Destiny first released. It's especially funny given the fact that Rahool would often troll players by turning their Legendary (purple) Engrams into Rare (blue) items. So in a sense, the message isn't wrong in saying that the million deaths you caused by farming still wasn't enough for Master Rahool.
That was before the change to the loot system which, in turn, led to the death of the loot cave, though. Now, with the loot system mostly (kind of) fixed, players must resort to playing Destiny the way Bungie intended, which I guess is less about farming for random items and instead grinding for reputation.
