Hi, just made the account for this question.
So we know that surges might have been responsible for destroying Braze( from the words of Odium so specifics and truth are not yet certain)
Because of this , or because people jut couldn't be trusted with such power, or combination of these reasons Ishar decided to place some requirements(checks) on the bonds/surges, i don't remember the exect quote but i think there was talk of killing this proto-Radiants if they didn't agree to this check(or mayebe spren, depends which side of the bond had to agree, maybe both).
So my main question is, how do this "checks" work. Do we have any information?
Was it magic based? Like are the Spren physically unable to bond without those checks now? or is it more like they were unwilling to bond without those check fearing some divine asswhooping, wich after centuries devolved into spren believing they can't do it any other way?
I think its safe to assume that this proto-Radiants didnt need to say oaths. So how did the spren bond people? Because i assume spren types didnt change, like Honorspren are still Honorspren so they would have wanted Honorable person to bond.
And most important, if it was magic based, it was done by Ishar= Bondsmithpower, so can Dalinar remove these constraints(if he is the correct type of bondthmith out of three(but he is supperBondsmith now anyway so mootpoint)? or by anyone holding Ishars blade.
P.S. we know that 3 bondsmith(s) don't have identical powers, but there are 10 Honorblades, meaning one for Ishar, so does ishars blade grant different/weaker/stronger bondsmith powers?
