Spoiler warning maybe?
So the unmade are spren right? And the keeper of secrets tells shallan to ask her son about trust, who im assuming is pattern when she refers to it, in oathbringer when shes at the gate.
Heres a theory and prove me wrong if u want my friends and i argue about it, were the unmade the original "higherspren" of honor like the stormfather, only of each order of radiant. But then corrupted by odium before the nahel bond started? Why she says they were made, then unmade?
