The descriptions are superb, striking a good balance between brevity and clarity. That's not easy, but you make it look easy!
If I had anything to nitpick, it'd be the five paragraphs in the middle where the "reflecting" happens. I know why it's there, but I wonder if there might be a way to keep the pace up while still sharing Brek'thar's thoughts on how he wound up where he was...?
The prose is excellent, though, flowing very naturally. Well done! I can tell you've done this before. :)
