He would've received a lot more than a slap from izzy if he woke her up like that lol

Lets assume that all who were at the inn know about what's going on? Or not- it's up to everyone. Either way, it will have to be explained to Durin,  Kayleth and The Red at least. But it would be as simple as Robert explaining that he got a tip from somewhere that the key to ending the war is up in the mountains,  and there are dragons in the way. 

On an ooc note, the goal of this quest is to retrieve an artifact, one of powerful, magic properties. The artifact had been discussed by the Co gm (who has disappeared) and i. I'd like to continue on that path, should he return, but if need be, I will tweet it a little. So if anyone wants to know a bit more about the artifact,  or thinks their character would know -anything- about it, pm me. It would help in the long run if at least one person heard of it somewhere in the past.
