Very nice! Either your tale is inherently more action-filled than mine (not really a surprise), or you're just good at making everything feel like action.
A couple things I noticed:
When he first wakes up, you casually mention that it's nighttime, and then move on with your description, but none of the ensuing description plays up the fact that it's dark. As a result, even though you said it was night, the scene I saw in my head was more of a twilight than a full-on dark.
Also, when Dren criticizes Garrik for not keeping his voice down, it feels hypocritical. As far as the reader knows, no one else was making any effort to keep their voices down. You emphasize it after that point, but not before.
After you've established the guttural language as the Drakkin's native tongue, it's not necessary to keep referring to it as "Drakkin tongue." We'll understand from context whether you mean the actual people or the language.
Why wouldn't Karrys have warned Garrik about Tul being in the tree before? Obviously she knew he was there, or assumed it from what little noise he made- why not warn him directly, before she has to tell him not to draw attention?
The fight scene seems to flow very well, moving smoothly from Gartren to Tul and back again.
Point of continuity: You describe Garten putting the tip of the sword beneath his chin (how exactly? pointing up or across?) but then, when he dies, the sword goes through his heart. I... don't think that's how it works.
You've done very well here, establishing the Drakkin as a formidable foe and worthy of fighting.
It definitely no longer feels like they should be the good guys, like it did when we saw the theives' meeting.
About the only thing I would suggest, other than the above issues, is to polish the descriptions. I know, I know... pot calling kettle, but still.
They're not too bad as they are, just clunky.
Oh, and I liked the map. Definitely gives a good sense of history and back story that I now want to know!
