Crimsonwood keep questions

I can't help too much since I haven't figured the connections out yet, however:
If you happen to find the map called Forgotten Path, the top left portal of that map takes you to Valley of Heroes. A flying mount could help a lot here to get to the top of Forgotten path.
On one of the 3 or 4 maps named Crossroads, the top left portal takes you to the Forgotten Path map.
Once you get the Map from the quest, the stone portals at top-right on any of the Crossroads maps will take you to the Forgotten Path map.

Actually, Stereo's map is still mostly valid except for Dead Man's Gorge:
