Is There a Fabric of the Universe in Peril?

I remember Mythwalker. Was that where like the Fabriels came from? Yes. I threw that one in the wood chipper and took a lot of the ideas. It had a really bad magic stuff. Some day I wanted to- Oh, I'm pretty sure the Shardplate was in Mythwalker too. And so, Aethers are still canonical to the Cosmere. They will show up. Then there was Mistborn Prime and Final Empire Prime,. which are the two I'm going to be George R.R. Martin for a day. That's sort of itavin'?!
