Hi there! You asked for a review, so I thought I'd go ahead and give you one! I left a lot of comments on your story already, but I generally don't like to leave critiques on the actual story cause I think it's bad etiquette, so I'll leave you one here, instead!
To start off, like I wrote on the story, I think you're a really fantastic writer and you have great instinct for describing scenes and lines of action in a way that is fun to read but is also easy for the reader to imagine which is great! Similarly, I think you're doing a great job building up and developing all the characters so far! Railynn has a defined personality, motivation, and I root for her! I also like Pik; he seems pretty ruthless, but also cold and intelligent which I like! I also really like that you didn't just dump a lot of inf on the reader by having a full paragraph about what faeries and all these other magical creatures are; you incorporated it at a good and logical pace.
One personal, nitpicky critique of mine is that I think the characters' physical attributes may be a little overdescribed. Otherwise, I think you're off to a really good start. My other suggestions would be to skim the story and look out for typos and certain sentences/descriptions that could be cleaned up a little.
It's pretty early on, so I don't have many critiques. Something I would look out for concerning Railynn is to consider how powerful she is, however. It's early on in the story and she's wicked strong (physically) I would just make sure that you balance out her power with some character flaws which it seems like you're already doing a good job with. You can also consider the kind of damage she can do to anyone she loves since she has such considerable power.
Otherwise, keep doing what you're doing! Your story is great!
