exploring the great northen wall

I've just started exploring towards the explorer title and i've already found a problem



Anyone know how to explore the circled area in the left picture? I want it to look like in the right pic

Play/run through the mission until you get to the cutscene where you have to run back to the wall from the charr. Instead of running back, run towards the gap they come pouring out of. That leads to the charr staging area, which is the foggy part of your map. Once you make it in there, the charr should leave you alone. You then have the 2 mins or so to explore.

Thanks !
