Thoughts while reading:
Wow, lots of points from me at the beginning. You get right into the scene with good details and enough good dialogue to keep it going. Perfect.
Some of the phrases you used just struck me as awkward. I could figure them out, it just seemed to disrupt the flow. Like this one: 'Even among those that would brand him as a heretic, there were so many Boone was guilty of' and this one :'which only increased the tension in the weapons that were pointed at him.'
'roldt' are we supposed to know what that means? I don't think it's a name...
Some fluffy, 'telly' phrases that can be deleted: 'reading Boone’s actions' 'Quickly analyzing his surroundings' 'determining which direction Boone had to run. '
'“Curse the Birthright!” Boone muttered' Which is it? is he yelling (!) or muttering? Watch the tags.
'Where were the stairs?' Great chance for internal thought. Italize it.
A lot of your sentences seem a bit too telly and too long and I would break your paragraphs more.
Ex: 'The second story must have housed the owner and staff of the tavern, which was why the stairs were hidden somewhere in the kitchen.' I don't care what's on the second story, especially if you are going to show me latter, so just have him guess that the stairs are hidden in the kitchen and go from there.
'And with those words, Boone proceeded to surprise, shock, astound, bewilder, and foil his captors.' How did he do that? Show me and skip the fluff.
'While Boone was generally quick to make witty remarks.' Never tell me if a character is witty in the narration. You might get away with it if another character says it, but mostly you are going to have to show me.
Overall impression:
Most of my stuff was nit picky and up to debate because I really thought it was good and moving right along. Just cut some of the fluff and telling details. And I am still lost on the magic system, but I never did read the prologue, so that may be where my problem is....
Good Luck!
