(ICECROWN) Cant interact with Hodirs son despite being exalted

Hi. I just purchased 50 hodir's sons token in order to be exalted at hodir's sons. The problem is that right now, i cant interact with hodir's sons at all. They are green and arent hostile to me but i cant buy any enchants or stuff. I tried going to Thorim at stormpeak in order to launch "Forging an alliance" but he wont say anything else than "Talk deathknight". I also tried lauching the quest chain from the beggining at K3 but im hostile to the blue girls in the arena ( because im exalted in Hodir's sons rep ..) .. Well it seems that im kinda stuck right now and was wondering if anyone had an idea (other than just slaughter all of hodir's sons in order to go back to hostile to them and go back to K3 ... )

Thank you in advance for your help and sorry for the bad english

Anyone ? Im still stuck with this issue

You need to get drop from killing storm giants to begin the quest line for Forging an Alliance. That is how you get the forge moved to there.
