I spent a good chunk of Rhythm of War getting annoyed at the Sibling whenever they argued with Navani about fabrials.
I wanted the tower working again. I wanted the Fused gone. And Navani was doing all this fascinating research while the Sibling kept objecting to things that seemed completely normal by Roshar's standards.
Then I realized I was looking at the whole argument from Navani's perspective.
We've spent four books seeing fabrials as useful inventions. Heating, communication, transportation, all these incredible things that make people's lives better. Of course we want Navani to keep developing them.
But from the Sibling's perspective, humans have spent centuries trapping spren inside gemstones and making them perform tasks without ever asking whether they wanted to.
And the Sibling is literally a living building that functions through a willing relationship with humans.
That last part is what got me.
The most impressive fabrial we've encountered isn't powered by imprisoning a bunch of unwilling spren. It's powered by cooperation with one.
I don't think this automatically means every lesser spren is suffering or that Navani should throw all her research away. We don't really know enough about what those spren experience to make that judgment.
But Navani doesn't know either.
She's so used to thinking about what a fabrial can do that she rarely considers what being part of one might mean for the spren.
And when somebody who actually understands that side of things objects, her first instinct is to defend the technology.
I still love Navani. I actually think this makes her a much more interesting character. She's brilliant, she's genuinely trying to help people, and she has a pretty enormous blind spot about the beings making her inventions possible.
What's interesting to me is that the Sibling isn't really arguing against technology. The Sibling IS technology, in a sense.
They're arguing about how that technology gets made.
I wonder if other people initially sided with Navani here, or if I was just too excited about magical engineering to notice the ethical problem.
