'Duty and the Beast' issue

So I'm experiencing a problem where I did my level 50 quest for Warrior and everthing was fine, now I'm level 53 and cannot find Broken Mountain for the next quest, 'Duty and the Best'. I went to the exact coordinates and looked up online several time but I just can't find him. When I go back to talk to Curious Gorge he tells me that his brother is still in convalescence. I was looking for him yesterday and I'm still looking for him today.
And it's worth to mention that I'm at the point in the Main Scenario Quests I'm at 'Acting the Part' which is for level 46.
