Although you are writing a fantasy, some of this is familiar, having watched documentaries about ancient tribes in South America who still follow the old ways. (Suggestion) In these documentaries, the outside world often brings problems. Maybe Darik's interaction with Humans could bring about conflict.

'perturbed' - I think the word you were looking for is protruded. (Mistake) 'shouts of alarm. The alarm horn sounded.' The word alarm is used twice, quite close together. (Suggestion) Use a thesaurus to change one of these. There may be places where a comma is missing or unneeded. If you read the piece out loud you will spot them yourself.(Suggestion)

This is a good first chapter, with plenty of signposting to how the story will progress.

My review has been submitted for consideration in "Good Deeds Get CASH!" .
