I could probably read Ishar part a couple more times. It's one of my favorite parts seeing him fight as a bondsmith. I cannot wrap my head around his goal though. When I go through my thought process goes to WoT. Like most people go to Tel-a-whatever dream world. Then some people step into it physically. This is how I'm relating what happens to the spren. Its like to the spren the physical realm is like WoT dream world and Ishar is forcing them through "physically". So instead of coming in their typical realm form like a normal radiant spren, Syl disappearing and showing herself to who she wants, the cryptics doing spacey awesome cryptic things on random surfaces. Etc etc. Instead he is bringing them in "physically" in their real body. I'm not personally relating it to hemalurgy. And I have this big hunch saying it has something to do with Connection. But that seems more like Kelek's deal than Ishar? Ishar could still want unbounded from the system. I dunno. Random thoughts. Very very interesting part of the book.
