A different reality

Apparently, within the sink hole is where the werewolves live. Not exactly within the sink hole of course, but this sink hole was basically the way to their home. This became apparent to the newcomers like Mark and so on, when the werewolves in the front had jumped in towards the sink hole a minute after the Alpha had opened it up…

Although the strong gush of wind that came out of the sink hole was strong, it wasn't strong enough to push someone high into the air. Instead, it was strong enough to keep someone floating, just like whenever someone's skydiving. This means that with proper form, one could dive within the depths of the sink hole, which is exactly what the werewolves did first after transforming into their human-like figures.
