I liked the third chapter. I start to care for David and George. I don't want to see them hurt or their lives ruined. You made me curious also. I want to know who this dark figure is. So I have to read on.
Your descriptions are very lively. I was able to imagine the village, the surroundings, the people. Well, I'm a big fan of LOTR. I have read all the books. That's why I'm quite familiar with an Elvish world. At first sight one might think your story is just another LOTR fanfic. But it is not. It is an original story.
The story is complex. Personally, I do like complex stories that are a bit of a challenge to the reader. You might repeat important details now and then, occasionally and sublte, just to make sure that your readers remember them and don't lose thread.
One question came to my mind. George was eager to enter the new world. Is he really able to forget his past entirely? Would not a memory, a good or a bad, disturb his mind? Not right now, a little later perhaps when he has settled in. This is up to you, of course.
I think it is very important that you stick to your very own concept of your story. I once wrote a chapter of a story not the way I had wanted to write it. I wanted to please my readers. I was very unhappy with where the story went and I dropped it after seven chapters and have never taken it up again.
Your story is amazing. I look forward to reading the next chapter.
