I'm enjoying poking around out in the Rift, but mainly because I like exploring. I can virtually guarantee everyone here that there is no Big Mystery that has been waiting to be solved for 2 years out there.
Remember, Drew whatshisname was just a fanboy writing fan fiction 2 years ago. FD might have thrown him a bone back in 2014 as a little Easter Egg, maybe made sure one or two systems were hand-generated to be a little odd, but nothing beyond that. The game engine couldn't support much else.
So, anyone expecting a big payoff for some awesome discovery of a "solution" to an intricate mystery is going to be sorely disappointed, unless FD have added a whole pile of material in conjunction with Drew recently.
Drew is playing this Salome character now in-game, apparently, dropping a whole pile of vacuous platitudes about exploration that are supposed to sound deep and inspiring, but actually read like a 14 year old Dungeons & Dragons game master's narrative. It's kind of sad.
Sure, I want there to be a grand and very clever mystery that is 2 years old that's just waiting out there there to be discovered and solved. But my guess, based on how badly botched the original Unknown Artefact clues were (they weren't even *there* until the patch...), my guess is that there IS no real mystery that is from over a year *earlier* in the game's development. It's just a Easter egg that is going to be hugely disappointing to everyone who has sunk hundreds of hours into the quest to "solve" it (i.e. stumble blindly on some random system or two in the outer arm beyond the Rift).
I don't blame Drew for trying to drum up interest like a good fanboy. And good on him, it got him the gig to be the official writer for the game (which didn't *have* one before? - lol). But unless FD has added a pile of good content to the mystery recently, my guess is there is barely anything to really discover. And remember, *good* mysteries can be fully solved by deduction - just ask Sherlock Holmes. They don't require hundreds of hours of random guessing in the vague general direction of the right answer.
