Great theorizing by Bsomeone!
Here’s a speculative question I’ve been mulling over: "What did the Cinder King whisper to Render at his Breaking that drove him into an insane rage?
That Zara is responsible for the Cinder King’s escape. Had she left the ten-pointed crown on the throne in Dar he could never have escaped, but she took the last point and now his power grows again.
That the Living God is responsible for the Cinder King’s power. The same power that let the Living God create nine chosen is the same power that the Cinder King now uses to break his enemies.
That the Living God lied to Valsim, he was never going to be able to defeat the Cinder King, merely slow him down. He was always going to be a sacrificial lamb.
