Hopefully they’ve created something great for what the darkness is, because the only time I recall someone from Bungie discussing it was this from Luke Smith “Here’s Luke Smith speaking to Kotaku on their podcast: “At a point, just totally candidly, we had no idea what [The Darkness] was. Straight up, we had no clue. We didn’t know what it was. For a period, we chose we were going to lump all the races, and you can see this in the tool tips in the game: “Minions of the Darkness.” And we had taken all the races and said, ‘Ah, they just all be The Darkness.’ But that’s not what the IP deserves. It’s literally not. And so, what we’re doing with Destiny is we are deliberately telling a story about the Light and what it means to be chosen. And as such, we are in the process of removing the term “The Darkness” from the game because when we are going to talk about Darkness next, we need to know what it is and have a plan for it. And we do.” From https://www.forbes.com/sites/insertcoin/2017/06/15/bungie-has-written-the-darkness-and-the-exo-stranger-out-of-destiny-2/
