[@Kho] What if we create or have characters who may later ascend for some reason or another?

Also, how did Zephyrion change the Codex when he made elementals. Did I miss that part?

That's a different story, and a bridge we'll cross when we get to it.
And yes, it's all in the IC. He didn't do it by directly taking the Codex, but just changed the inherent laws of the universe so as to account for 'flickers'.
