@Cuttlefish:
I don't...uh, share your idea of how *meaning* works. It's like saying that Moria has no meaning, because the party gets through it. Why not just have Gandalf wander away? It all is leading up to a plan that Frodo abandons anyway!
That's a poor example, though. Moria and the loss of Gandalf triggers the beginning of the Fellowship's division, and all said and done, the whole thing escalates into a point where all the storylines converge on the same point, which is, as I recall, the Black Gates and Mordor.
They could've always just used the eagles, though...
Like, WLW is the title character of a book. He kills Maithanet. His existence lets the reader get the POV of a destined character, foreshadows Sorweel's transformation, etc.
Neither of those things actually have any consequence for this book's conclusion, though.
Captain doesn't matter, because Galian killed him. Galian doesn't matter, because Mimara killed him. Mimara doesn't matter because she didn't, I guess, kill Kellhus?
Well, Mimara
might have mattered, but that's another thing - she doesn't matter because of her personal journey, the ways in which her character grew and changed. She matters because she has the Judging Eye, something she had from the very beginning (at least I think so? Definitely after she seduced Achamian). Do you think anything about TUC's conclusion would have changed, had Mimara just straight went to Kellhus from after meeting Achamian for the first time, and did what she did at the end of the book? Again, I do hope that her storyline will yield consequences for the next series, but so far, the Judging Eye has been a gimmick (that I am not fond of) and she hasn't been influential at all.
The point I'm trying to make is that the way you use whether or not characters 'dead end/serve any purpose' feels super reductive. Like, does Proyas 'matter'? On the one hand, obviously yes. His loss of faith, struggles, victimization, betrayal, rescue, execution...are given dozens of pages. On the other, lol nope! His life's work was delivering an army that was defeated.
Don't get me wrong, I am not saying putting up this whole consequence debate as a means to discredit the storylines, some have been really worth the read for the journey alone (as I said, the Ishterebinth storyline, arguably the least effective one, was my favourite), but when you put it down to its bare... yeah, that's pretty much it. Proyas hasn't influenced the ending, and what little influence the Great Ordeal had was either negligible or understated.
Think of it in Star Wars terms; the last movie - the confrontation Luke has with his father and the Emperor has virtually no consequence for the victory over the Empire. That doesn't make it any less enjoyable, but in my opinion, that is a narrative weakness.
