/// It's an excellent analogy indeed. I also like the bubble inside a sea of chaos metaphor (so it's not floating on a sea of chaos, it's INSIDE). Chaos is all around. If you strech the bubble too much, as the godlearners did, as the lunars do, it might burst. Then you'd better fix the hole real fast or reality as we know it will fade back to... primal ooze.
Wow! That's one of the best analogies I've heard in long while!
