<During the Taken King, the Hive and the new enemy, the Taken, were fully explained. During Rise of Iron, the Splicers of Fallen houses and SIVA were explained. During D2, the Cabal lore was blown open, but not as much as the Hive. During Forsaken, the Scorn were explained and the Awoken on a BoS level. So what's left to explain? - The Fallen - While many things are heavily implied, the EXACT formation of the HoD is still unconfirmed along with many pre-Whirlwind traditions and culture. - The Vex - This is self-explanatory. CoO didn't really reveal much that we didn't know. - Savathun - As next year closes in ever so slowly and she's been revealed to pretty much be a mastermind behind Forsaken's campaign, Oryx's sister has some explaining to do. Specifically on how she was able to Take. - Quria - What does it want? - The Drifter - Who exactly is he and what EXACTLY is he hauling in that massive ball? - Black Armory - How have these people not been found? - Penumbra - What's our final Trial and why is the Leviathan concept art for Penumbra different? Is the ship closing its maw? - Lysander - I mean I don't really care but some do. Any attempt at overthrowing the City right now, however, is kind of a dick move and uncalled for considering what we're up against. - The Collapse - Self-explanatory. Some are able to call major events, but none of the details. - The Nine - You get the point. - The Jovians - survivors of Cis-Jovian colonies but also transformed like the Awoken were but still harmed by Light? What happened? - Nezarec - Why are there so many mentions? Does he have any significance besides being part of a seemingly widespread cult and what's with that Nezarec's Sin Ornament in Forsaken? - The Darkness - What is IT? What lives in those ships? Why did it take residence outside of the Galaxy? Anything else?>
