There's 3 quests that I have found that you can grab at the inn: Lieutenant Paval Reethe, The Blackened Shield, and Suspicious Hoofprints. They are all turned in to Krog in brackenwell.

The tiny badge sitting on a plank inside the in starts the short lt. paval reethe chain in which you go question him. You get jumped by 4 level 36-37 guards and you have to kill them all to get credit. The ogre you're with wont help unless you move far enough back that he gets aggro first. If he dies you fail but you need him to take some hits if you're soloing it. If you get initial aggro he wont help. Once you kill them you go back to Krog and the chain ends.

The shield attached to the chimney starts the blackened shield chain. In this you get sent to another NPC who tells you to get some acidic venom sacks from darkfang spiders. Once you get them he is able to read the name Mosarn from the shield and sends you to Krog who sends you to Mosarn on Hunter's Rise in TB. Mosarn says he doesnt know anything and the chain ends.

Suspicious Hoofprints seems unfinished or broken. Krog says in gray text when you turn in the quest to him that he will dispatch a scout to see where the hoofprints lead and the quest ends. There is no chain. I went back to the inn to perhaps look for the scout to no avail. I even tried heading in the direction the tracks seemed to be facing, also turning up nothing.

As far as I can tell thats all you can do for this quest. Kind of annoying because I wanted some closure as to what the deal was :/

this quest works fine...

u get 3 quest from the inn.
when the poison has been collected and they are done, head southeast from brackenwall village. at the road you'll find a ogre with a quest, and he will lead you to Paval Reethe.
After some talking back and forward, 4 theramore guards show up and you need to kill them (i soloed as 37 rogue, easy)

return to brackenwall and now you get quest to go to thunder bluff where the quest finally ends at Mosarn at 'The hunter rise'
