Did I miss something?

I just got a new character into Post Searing and when I got there Captain Osiric is there with a quest. Well, I had to log before I could talk to him. When I cam back he was no where to be found in Ascalon. Anyone know what quest he gives or what he's for there? It's been a while since I've been through this part of the game so I can't remember if he's important or not.
