SO basically, the power of gods seems to be practically pure Invsture right? And in ROW Sezth damages a Heralds blade which were given by Honor, and so it would probably be safe to say a little part of Honor. Syl has in the past said the spren were basically little bits of divinity, which probably means they are parts of Honor. SO what would happen if a spren were to be stabbed by Nightblood?
