Sons of Hodir quests

Hello everyone,

I have been looking all day and cant seem the find any quests. Ill sum up my problem: A while back i was questing in storm peaks and started the Sons of Hodir quest chain. Right now i'm at 3000/21000 to exalted. I remember that the quests just ended and i moved on to icecrown and now that i want to purchase items from the quarter master i face a problem. When i enter their area, all of them are green but not clickable. I've looked EVERYWHERE in storm peaks to a quests but no area could offer me any quests succeeding where i left of. Anyone has any ideas?

Thanks in advance everyone!
