I would assume so, as Nightblood seems to take Breaths from his wielder over time while drawn, not all at once the instant he is drawn, based on what we see in the climax of Warbreaker (he drains Vasher progressively over the course of the fight where he's used). But I'd doubt that it's possible to draw and then sheath him again so quickly that he wouldn't take any Investiture at all. After all, Nightblood's always hungry.

IIRC, the very first we ever heard about Adonalsium was in the Hero of Ages epigraphs (which alludes to the shattering but doesn't really spell it out explicitly) and the online Q&A session that followed HoA's release.

Per WoR, Dalinar realizes while fighting Szeth at the climax that he couldn't have defeated him that night; I'm inclined to defer to Dalinar's judgment, so I voted for Szeth.

IIRC, it's explicitly mentioned in Alloy that Hinston's death wasn't planned and he was supposed to take over the house for his father and run it on his behalf - he died unexpectedly, but Edwarn's plans to fake his own death were already too far advanced at that point to stop, so Wax becoming heir and coming back to take over House Ladrian then became something Edwarn just had to deal with. Hinston's article on the Coppermind is backing me up.

And so, it's time for the last(?) installment of our little series - Stormlight 5, as based on the opening lines of the prologue Brandon has already posted! Of course, some would say that seeing the future is of the Voidbringers... but if so, the Voidbringers would seem to have some very, uh, interesting ideas about what lies in store for us in the next volume (and go into first person for a few paragraphs for some reason). And like previous incarnations of the bot, are struggling with what, exactly, characters' relationships to each other are. But at least Bridge Four seem to be well-fed this time around. Spoilers (?) to follow:

And now, it's time for Rhythm of War, once again using the opening lines from the prologue! In which Gavilar (who has apparently renounced his throne to become an ardent) and Navani talk politics, business, and sorcery, while the bot is very confused about the exact nature of characters' relationships.

And now, for Oathbringer! In which Eshonai leads an invasion, Dalinar has trouble with people who like pointy hats, and apparently Bajorans are involved somehow?

The original Mistborn trilogy (Final Empire, Well of Ascension, and Hero of Ages), the currently ongoing Era Two/Wax and Wayne series (Alloy of Law, Shadows of Self, Bands of Mourning and, coming this fall, Lost Metal) and a couple of short works in Arcanum Unbounded (most obviously the novella "Mistborn: The Secret History") are what's out now. At least two more full arcs, Era Three (modern/urban fantasy) and Era Four (space opera) are forthcoming. And of course the rest of the Cosmere is set in the same universe as Mistborn, but not actually on Scadrial.

Stormfather and Nightwatcher, I would assume. Stormfather is Honor's Cognitive Shadow/successor, Nightwatcher is described as Cutlivation's daughter and per WOB is to Cultivation as the Stormfather is to Honor, and the Sibling is depicted as a blending of Honor's and Cultivation's power. They're also all "siblings" in a more poetic sense, as the three Bondsmith spren.

On a whim earlier today, I decided to see what might happen if I fed the opening lines of the prologue of WoK into a bot and watched what it came up with. Bizarrely, it seemed to have some idea of what the Stormlight Archive is, who some of the major characters are, and even concepts like bridge crews, lighteyes, spren, etc. It also managed to be marginally coherent, at least until the character limit ran out. Of course, being a bot, it has no idea of the context of anything, and so ended up producing a twisted funhouse mirror version of WoK where Kaladin and Bridge Four are trying to build a bridge under the not-so-watchful eye of a nameless king, while Kaladin is apparently pretending to be Sadeas's son for some completely inexplicable reason. Oh, and Szeth may be the Dragon Reborn, but I'm not entirely sure on that. The text I gave it was, of course, "Szeth-son-son-Vallano, Truthless of Shinovar, wore white on the day he was to kill a king." The bot I used was here:https://app.inferkit.com/demo As for the "story" itself, behold behind the cut! And yes, I know it cuts off in mid-sentence. That's part of the charm;).

Considering the qualification "meaningful," I would assume that this is the case; Wednegon was the last (or one of the last) to be powerful enough to face TLR on something vaguely resembling even footing, while by the time of the later conquests he was powerful enough (with large enough numbers of koloss, allomancers and Inquisitors + conscripts from places he'd already conquered + increasing familiarity with his own abilities should he choose to take the field himself, etc.) that he was able to pretty much steamroller any and and all opposition. Considering it was Tindwyl who added the "meaningful," there may be some of her biases creeping in as well; ie Wednegon was one of the last whose resistance to the Final Empire was significant enough to impress her, personally.

Depends on how you're judging "favorite". Mistborn (the original trilogy especially) is what introduced me to Brandon's work, and it has a special place in my heart that is unlikely to ever be challenged. On the other hand, by almost every objective metric, I think Stormlight is the more accomplished work. Since those two aspects can't really be judged against with one another, I'm going to go with a Mistborn/Stormlight tie.
