My favorite god, Sazed/Harmony, in my recent reread I got a bit angry at him because he didn’t let kandra be able to reproduce, but he let the koloss be able to do it. And I’m wondering if there’s a way he could have allowed that, but he chose not to? And also if there’s a way that it could happen in the future, so that two of my favorite people could have a baby?
There are a couple things that he was facing, and let me walk you through his philosophy on this, which you are allowed to disagree with. I want, for every character I write, there to be things they do that you disagree with, because otherwise I’m writing all characters to be the same person, if that makes sense.
The kandra have immortality and are able to perpetuate their culture by being immortal for as long as the individuals live. The koloss don’t have that, meaning that if he didn’t make koloss able to breed true, the entire people vanish in one generation and all culture associated with them. And so because of that, he took the extra effort to change the koloss to allow for this sort of thing. But he did it in such a way that they would not have to have hemalurgic spikes, because the idea of making new hemalurgic spikes is extremely distasteful to Harmony. Reusing old ones is a thing he was willing to allow, but new ones he didn’t.
Could he have changed the kandra to be similar? Well, the answer is kind of a fairly... yes, but they would no longer have been the kandra, they would have been rolled back to being what they were before the Lord Ruler. And so they basically would stop being what they are that makes them unique as a culture. And he decided not to do that.
You can disagree with that, and I think there are some pretty valid arguments against the choice he made, but that is the choice he made.
Is there a way going forward? Yes, this is theoretically possible.
