The son of hodir repotation

I buy with triumph my repotation to exalted and i cant buy my enchant for shouders (Greater Inscription of the Axe) can someone help me ?
The vendor is there but i cant buy it :)

It's been a while since I've farmed reps with them, but you might need to unlock the quest chain because you could be phased out. Also, once you complete the quest chain, you might also need to uncheck the "At War" box on the reputation page somewhere just so you can talk to the quartermaster without him trying to fight you.

thank you!
