Problem with hidden quest

[Ashba]

This was probably asked a thousand times...

I found one of the hidden quests (Rory's), but i after we're done with our convo i have no idea where to find the enemy party he talks about. (The Iron Islands are gone in my save). Also, there aren't any instructions in my Notes tab.

Is it broken and i have to wait till beta 10? or is it because the ironborn are gone for good?
