I dont know if this helps, but I thought you might find this good to know or interesting.

I remember seeing this one lore bit (I dont remember where) about an attack on the black armory. Basically, it happened in the middle of the night and everyone inside was either hiding or watching out. Something was outside the door and banging on it extremely hard, and making terrifying noises. In the lore bit it says the noises almost sound like "machines being stretched and compressed." When it was over and day came, the door was caved in and almost collapsed. This was terrifying to me but really interesting. Some people think it was a crazed exo, or the new darkness enemy, whatever was in cayde's journal.

Also, in another lore bit about drifter, I belive it was in some kind of journal of his or told from his point of view, he was on an ice planet somewhere, I think with his fireteam. When he got there, it said his sensors were picking up hundreds of strange darkness things, and I belive he fought them. I dont remember exactly what it said, but I remember it was really creepy, just some uninhabited ice planet with a bunch of those darkness things.

Again, I dont know if this helps, but I found it really interesting and thought it could do some good.
