[quote][b]Vanilla:[/b] 1) We still don't know who the Exo Stranger is, who she is talking to, or what she is doing. True. 2) We know nothing about the Vex's origins, their motives, or their leaders (besides Atheon). They are radioloria. Their motive is to become a fundamental law of the universe; to find an Emperor for all outcomes. 3) We don't know what the Darkness is (and neither does Bungie atm). Yes they do. 4) We don't know anything about the Traveler's true nature or origins. True. [b]The Dark Below[/b] 1) Omnigul can undo her death, given the right conditions. We don't know what these conditions are, therefor it may be possible for other Hive to do the same. We already know that they can. Read the BoS. This means Crota and Oryx could potentially return as future adversaries. They died true deaths in their personal Throne Worlds. This is still a foggy lore area IMO. [b]House of Wolves[/b] 1) SIVA being used to resurrect and improve notable Fallen foes means the same could be done for Skolas at some point. Combined with the Vex tech he used, he could be immensely powerful the next time we fight him (probably worthy of becoming a raid boss). Eh. It can revive Sepiks (100% machine) and Taniks (33% machine). Probably not Skolas (0% machine). [b]The Taken King[/b] 1) Oryx's Ravenous Heart is now in the Touch of Malice, which will be seized when the Cabal kick us out of the Tower. He could still return. Debatable. 2) We still have the Crystal containing a piece of Crota's soul. Maybe we could turn this into a weapon too? If we do, I hope it's a sword like the one Crota wields in Crota's End. Not really a loose end. 3) Eris Morn leaves the Tower between the conclusion of The Taken King and the Cabal Invasion. She's out there doing something, but it might be a while before we find out. True. 4) The Awoken Queen is MIA. Presumed dead in-universe, but we know she's alive somewhere. Personally, I hope she comes back in disguise, so we don't realise that it's her at first. True. Plus her plan that transcends death and spans universes. 5) The Queen's Brother is off doing something with the Fallen, but we don't know what. Something with the Kings. 6) Taken are still an issue. Cabal from Red Legion are being Taken, this means they have a new leader with the power to Take. A bit too soon for Oryx's return, likely someone else. True. [b]Rise of Iron[/b] 1) SIVA still exists, it's still a problem, and the Fallen may not be the last to abuse it. True. 2) Aksis wasn't the one in control after he Perfected himself. Someone else was pulling the strings, and besides Rasputin (highly unlikely) we have zero suspects. Charlamagne? O___o === Have I missed any? Please let me know in the comments![/quote]
