How to find "a certain cube" in the main quest

[Slovier]

So I found the Shimmering Metal Alloys for Kurai in the Old Starling Mine. Now my map marker shows a place in the northeastern corner of the map but that area is very secluded with big mountains around.

There's no way I can walk into there, I tried from every direction. I tried several caves and other interiors in the area. There was some cool loot but no way out to the place I need to go.

So, people who have completed that quest, can you help me get there?
PS: I know map marker is supposed to show me the entrance to the area, which is what happens in most cases in quests like this but it isn't. So, help?

You should probably post this in the Enderal:Quest Help section rather than the general SureAI section. It would also be helpful if your subject line uses the specific name of the quest you are on, as noted in your journal.

Behind the Myrad Tower of the Wellwatch is a path leading up towards the Thalgard area.

I had trouble with "Find a Pyrean crystal cube" as well.
