Hadn't you once stated that Iamos began his journey in search for Aedus, wishing to be taught by him? That's one big change! :P
Other than that, yipwa! You finished Segment 1! And with that the journey begins. Let us go everywhere. It loved the final part, though I need to reread the ship's description to understand what you were actually saying! :P I hope Rainer survived. I like all the mystery about Aedus, Rainer and Iamos's parents.
Some comments:
At some point, you said Elepharian. That is logical considering the name Elepharia, but I'm not sure it's correct to use the term since the term Elephanter already exists.
Is the map not blank? Not that I mind your changing the plot a bit, just wondering.
