The Pocket Caves are Created

The ground soon becomes unstable, tearing apart the spaces underground, and forming vast cave systems that expand into every inch of the Nightlight Zone. These caves almost tore apart the landmass that makes up the Nightlight Zone, but with assistance from the Watchers, they slowly became stable. It is said that the caves stretch all the way to the bottom of the Nightlight Zone's landmass, leading to a place no living thing has ever seen before.
