Ok...I figured out the true puzzle to unlock the quest and get your hands on this amazing gun. I won't be like some douches that try to keep a secret in this game for themselves. Step 1: Play the game. Step 2: Wear tinfoil hat then read all grimorie cards for clues and over analyze everything in the game. Step 3: Create conspiracy theories. Step 4: Be too dumb to figure out how to actually activate quest line. Step 5: [b]Wait until Bungie says "You mean these idiots still havent figured this out yet? It's not that friggin' hard if they just worked together as a community instead of putting all their efforts into elaborate troll posts and photoshops. Fine just give it to them before their tears raise sea levels and flood the coast".[/b] Step 6: Collect your hard earned exotic I believe that about sums it up. This should also work on any difficult to obtain inventory in the game.
