Is there a WOB on spren/splinters of other shards interaction with Surgebinding

[MarcieIsForager She/They]

Like say Harmony were to during like Cosmere endgame invest Roshar and create like Ruin/Preservationspren and maybe a mix. Say Harmony/Discordspren. Could they be bonded and create a Radiant. Like maybe if the Honor component is strictly necessary for a nahel bond you could have like 90% Preservation 10 % Honor.

Do we actually have something on that?

[Quantus he/him]

Yes, several WOB's imply that, in theory, pretty much any pure investiture being could learn to form a Nahel Bond like the spren did.   The Seon Bond is essentially the same thing.  For the most part it may or may not grant powers, but it's not just a Roshar thing.

Is the bond between a seon and its master similar to the Nahel bond between a Surgebinder and his spren?

Brandon Sanderson (paraphrased)

Yes.

How important are bonds like the Nahel Bond and a seon bond in the Cosmere?

Brandon Sanderson

I'd say very important.

Thadamin

Is this kind of bond relatively common or is what seons, spren, and Nightblood do little more rare among Splinters. I'm specifically talking about the act of making bonds not a giving of magic powers really, that appearing to be function of Roshar. Also regarding your post about Stormlight 3 I am personally okay with 2000 pages if need be so make the chapters as long as you want.:)

Brandon Sanderson

The bonding is basically the same mechanic, regardless of the world, just with different flavoring. Roshar isn't the only place where the bond gives powers; it's a matter of what's stuffed into the soul, and how.

Questioner

If an Elantrian bonded to a Seon were to travel to Roshar, would that act as a Nahel bond?

Brandon Sanderson

It would act very, very similarly, yes. But it would be like... it wouldn't necessarily do the exact same things. Like if you've got two radios tuned to a frequency, they won't necessarily pick up another radio frequency, or things like this. I don't know, that's a bad metaphor, I'd have to think of a better one. But it would be treated exactly the same way but it might not grant the same powers.

Because of Kelsier's status as a Cognitive Shadow we've been wondering what wonky things you can do with him being like that and so-- Hypothetically, purely hypothetically, could a Surgebinder, could somebody form a Nahel bond with him?

Brandon Sanderson

With Kelsier? We'll RAFO that. We will definitely RAFO that for now

Footnote: Brandon has previously stated that this is possible at OdysseyCon 2016

Could Kelsier theoretically bond with someone on Roshar?

Brandon Sanderson

Yes.
