Very short for a second chapter (or first chapter following excusably short prologue; I think it would have been better for you to wait until you had more to post it), but other than that good. I noticed a few problems, however:

“Izen was so concentrated.” This sounds a bit odd to me. Concentrated is also a synonym for condensed, and this is how I first interpreted it, which I can see later in the sentence makes no sense. I think that “Izen was so focused” would work out much more nicely.

And there’s a typo with a word “hurriedly” in the third paragraph.

This whole sentence isn’t entirely clear: “He sighed relief when he made sure it had only been lightly sprinkled and got himself off the rocks and back to the pier, it was getting late anyway.” would sound clearer “He sighed in relief when he saw that it had only been lightly sprinkled. He rose from the rocks and went back to the pier; it was getting late anyway.” This isn’t too good either, actually, but I’m tired.

Well, I have to go. Keep it up, I look forward to the next chapter!

I like this a lot so far. The words seem to flow very easily, and I can really understand how the character feels. Update soon, I'm really excited about the plot.

This is a really nice first chapter; I like the setup of Izen's settings and characterization. I can really identify with the whole thing (being a writer too) I really liked it, so update soon.
