Spren bonds and orders

[Impact he/him]

So we know that Sigzil broke his windrunner oaths and eventually bonded Aux. Everyone assumes that means he became a skybreaker.

 

We also know that the bondsmith spren are all unique, yet provide the same abilities and order. 
 

Especially now, knowing that an object like nightblood can provide any set of radiant powers, it starts to make me wonder if bonding a certain spread means you have to be that order. I’m wondering, essentially if Aux could have accepted, wind runner, oaths, even though he is a high spren. 
 

part of my evidence, for this is that at the end of sunlight, man, nomad seems driven by protection, and not law, and that is what begins to give him his powers back. My back up theory is that Aux managed to become a windrunner while six over became a skybreaker

My guess it has to do with some kind of resonance. Frequencies seem very important in the Cosmere (tones of Roshar, pulses for metallic arts). The Radiant has their own “spiritual frequency” and so do the spren. If they match well enough, they can start to bond and then shift more into alignment with one another, kind of how Navani and the Sibling brought their tones into alignment to make one tone, Towerlight.

 

So maybe it’s like Windrunners are from 100-102 MHz (you know where the popular music is) and Elsecallers are around 90 MHz (news and NPR). I’m sure spren and Radiants can stretch outside their normal band but it would be unusual for them to resonate outside their usual band of frequencies. I didn’t use Skybreakers in my analogy because I don’t know what kind of music they’d be.

To circle back to Aux and Sigzil, I think it’s more like Sig is both Windrunner and Skybreaker. Aux helps him tap into the Spiritual Realm and Sig will probably always have some connection to Windrunners, unless it’s severed by someone else.

[Nitpicking]

Sigzil is a walking (flying) paradox. He broke his Windrunner oaths to protect someone who could not protect herself, Vienta, thus affirming them. Which rather goes to Adolin's point, that he still feels obligated to do everything he promised as a Windrunner, even if he broke words of the Ideal.

Sigzil also specifically talks about keeping promises even when oaths fail. 

But I think it might be simpler. Szeth and Aux both discovered that there are other Skybreaker oaths in Wind and Truth. As I understand it, those oaths are more about devotion to justice than to the letter of the law. Saving those who have been unjustly condemned by a tyrant matches those oaths just as well as those of a Windrunner. And in fact may more concretely call for that tyrant's overthrow.
