Not a bad first two chapters, but the attempt at what I'll call High Prose has this story feeling clumsy, at least to me. My suggestion is to tone done the ostentatious narration a bit, watch your tenses and punctuation, and explain a bit more of what is going on (i.e. Sidhe, Daughter of Eire, etc) Have fun with this story, but don't get lost in overworked narration.

Hermione and Harry will research the terms you are looking for. Especially after part of the next chapter.
