The past and the future....

Problem:

For your map you went with the post-Conjunction core. Dorvinia, Gundarak, Arkandale would have appeared at different times.

Personally, I've always wanted to do a Book of Ages featuring fallen lords, old versions of the Core and rules for alternate timeperiods and possibly alternate timelines.
One of them would be the 714 period with no Verbrek or Sithicus. Instead, there would just be Mist (just because a land isn't there doesn't mean there's a gorge).
The locals would assume it was still forest, since it was surrounded on all sides by forest and travelers didn't vanish into a hole. Might be known as the Misty Woods or something and thought of as particularly dense and frightening forest to explain not going through.
