Does anybody know if people in Orden are capable of finding entry into the World Below via mundane methods, or does it always require planar transportation magic to move from one manifold to the other? And by mundane methods, I mean something like. If you travel far enough below the surface of of Orden via the navigation of a cave system, or dig down far enough through the use of mining equipment, would you eventually reach a point where the manifolds overlap, and be capable of simply walking into the World Below from Orden?

Orden and the World Below are very close to each other. Their solutions are so similar they share many instances of bilocation. So, no, you cannot just dig down far enough and end up in the World Below. But some caves, even tree hollows, are entrances.

Sometimes the solutions change so rapidly, a place that was in Orden "shifts" into the World Below over the course of only a few weeks. Basically, it's like the time holes in Time Bandits. If you knew enough about Differential Manifolds, you could literally lay the solution down on top of a map of orden, and it would show you exactly where the instances of bilocation are.

Though the relationship between the two manifolds changes over time, so your map would slowly go out of date.
