Crimsonwood keep questions

But how i get to the map after Dead Man's Gorge?

IF you have a flying mount or a job with extreme vertical teleport or jump, and assuming the rest of Stereo's map is still valid, the best way would be:
From Haunted House map take left portal to Swamp Bog
From swamp bog take left portal to Crossroads 2
Fly up to top level of crossroads2 and take right portal to Forgotten Path
Fly up to top level of Forgotten Path and take upper-left portal.
I can't check this right now, I should be working.
