Western Remnants

There is a Border distortion over all of the Remnant.

As Arc gains altitude he sees no one atop the wall. The wall does have a walkway down it's middle and slightly raised and covered structures at the corners, but no one is anywhere on the wall. Scanning the immediate area around the team shows no hidden threats as the dinosaurs look to Give the buildings and the southern path a wide space.

Getting a bit higher and closer, careful of the border which is noticeable but not clearly so when looked at from above, Arc scans the interior. The first thing he notices is that the interior of the Remnant looks to shift and change as if shadows from clouds drift across it. As the "shadows" cross over the interior the building shift from looking grand and new to nearly complexly ruined. Equally surprising is the fact he can not see any creatures inside despite seeing the guards from above. Your flight seems to have caught the attention of some of the goblin guards who taunt and encourage you to "Just fly in" with shouts and gestures.

Borders: Created by or during the Shattering divide the lands like crack on a sheet of thick ice. These are theorized to be cracks in the Mortal realm where extraplanar influences leak into the mortal world. At the beginning they were much easier to detect but also much more dangerous. Many who entered never came back. Over the last 50 years since the Shattering they have been examined and appear to be sealing themselves and are not as easily noticed. Some are nearly indetectable and not noticed until crossed while other are clearly marked by sudden transitions in terrain or weather.

Crossing Borders subjects you to the forces of the other Realms but allows passage to other lands, but not always the same destination. You can leave form A , arrive at B, then recrossed and arrive at C. Many of these changes in destination seemed fixed and predictable and often formed a cycle. Scholars equate this to the lands now acting like pieces of wood floating in the sea of the planes. The Mortal Realm did not fully shatter so that the pieces still bump into each other but and they float the pieces touching shift positions.

This fact was exploited by travelers and merchants who had access to magical aid to cross safely and reliably. Fortunately the Borders have calmed greatly so magic is not needed to cross them safely. However it is still used to ensure arrival and departure points are fixed. Crossing a "Wild Border" is considered foolish and risky. The effects of the recent Border Storms are examples of what might happen if you cross a Border at an unregulated point.
