Warped Ways were somewhat of a natural manifestation, though it was only possible of spatial tears. It was just a very unstable version of Warp Gate, which formed under some unfortunate and unexpected circumstances.
There were dozens of them in the rift, which made it quite hard for one to judge how huge the whole place was, as there could be more of those warped ways undiscovered in the desolate land.
The main camp was actually founded surrounding one such warped way. After spending a great deal of resources, the arcane society managed to keep it under control. However, the one they were creeping towards was far from being under control.
