I'm about 15 points away from Master of the North. The two areas I need to finish is Battledepths in HM (red flag post) and Kathandrax in NM. I'm not sure what to do exactly in Battledepths for it to be completed with a gold flag post. I went to Heart of the Shiverpeaks for it but on my map it shows the open chest indicating it's completed. Do I have to VQ all of the enemies in Battledepths?
