Here's exactly what you're trying to quote: "However, in order to unlock the gun, players first have to collect relics of the Golden Age which have been scattered across the various locations of Destiny. After players bring these pieces back to Banshee-44 (the Tower’s gunsmith), the ancient artifacts trigger a memory in the ancient Exo gunsmith, and he will invite players on an odyssey to repair and reactivate one of the Taken King’s most striking exotics. Bungie doesn’t want to spoil the story content of this mission, but it did say that there will be unique tasks and objectives required for completion, which might even include puzzles that are too hard for any one player to figure out on their own."
