I had an idea, and I'm leaving it loose because I don't plan to go anywhere with it, but I thought it was cool.
What would happen if the One is very similar to Father from Ellimist Chronicles, except instead of assimilating bodies and everything, just minds and thoughts, and Jake becomes to The One what Toomin was to Father, and it advances similarly. How would Jake handle it, assuming he escapes in a manner like the Ellimist? If he made a ship to go around the Universe to do good (or evil), how would Crayak and Ellimist interfere, if they did at all? How would Crayak and Ellimist react if a third joined their ranks, except he wasn't bound by the rules of their game? It could be interesting how he would try to change history, and its consequences.
I know it's pretty far-fetched... but why not? I figured the idea did little if I just threw it in the back of my head in the "Random Junk" box.
