Hey all. Not new to the Cosmere but new to the forums. My wife and I recently reread rhythm of war. I had a though in anti investiture. We know it exists and has a rather explosive reaction to normal investiture. If we can assume investiture is from Adonalsium could we assume there is a being of anti investiture. Or am I missing a mechanic here (which I totally could be ). Or ateast the potential for their to be an anti shard?
