The loot cave has been abused by Destiny players for weeks until the inevitable nerf by Bungie. However, they have left a special message for players who went back to the cave accidentally or for some other reason.
As soon as you click on disturb the remains, you will hear a creepy voice that says, “A million deaths are not enough for Master Rahool.”
Now, master Rahool is the cryptarch in the tower to whom you went and decrypted all those engrams. Did you get any good gear from it? Probably not because he didn’t give players anything pre-patch.
Still, it’s a fun easter egg and you can find the video below which shows what you can encounter in that cave.
