The beginning was far too cluttered. Mainly with indistinguishable people, as has already been said, but also with references to actions. There was something about tables that were moved around that was only mentioned once and then never again. Then there's the fact that noone remarks on the bloke with the bloody knives, they all seem to take that in stride when I would expect at least mild interest to show.
The setting isn't at all clear, first you think it's a normal urban setting, then you think urban fantasy, and then you're completely confused.
A longsword made of copper?
When Lias goes to get the necklace he falls, grabs the necklace, and falls again, without standing up in between - or did I miss that?
The Warden is either healed far too quickly or described as far too wounded. After that fight I would have either expected him to croak, or to remark on his miraculous recovery.
A better introduction would have been in order, even only a few short moments of talking would have sufficed, something to better establish setting and characters.
That said, the pacing was excellent and made for a very good read. The flashbacks were a bit irritating, but in a good way. They seemed to fit in quite well, and they gave just enough information to leave the reader slightly confused but very interested to find out what the hell is going on.
