Something that has been bothering me for a while, and some other's I've seen on the shard, is the number of Bondsmiths. Two would align well, one for Honor and one for Cultivation, or ten at one for each order. Basically, three completely throws out the symmetry of numbers that is really important on Roshar.
My question is, what if there used to be more Godspren before the KR came into existence?
We know from a WoB that a lot of the spren existed before the shattering, and thus before Honor and Cultivation came to Roshar. We also know that the unmade existed before being unmade and reforged with Odium's investiture.
My theory is that when Adonnalsium made Roshar he made ten "Godspren". Sometime after the shattering, Honor and cultivation came and either created a Godspren (Possibly the case with the Nightwatcher) or upgraded a lesser spren into a Godspren (As we know from Oathbringer happened with the Stormfather.) For a time there were 10-12 Godspren, depending on the order of events in the timeline. This would be the original 10 for Adonolsium, then one each for Honor and Cultivation.
Then Odium comes in and unmakes 9 of them. (Following the prevailing theory, the Sibling would be the only one of the original 10 to escape.) The unmaking process would likely destroy most of the spren's ability to think while odium's investiture would put the focus on emotion that we see from the Midnight Mother, etc.
So What do y'all think? Feel free to completely obliterate this theory if it's wrong.
