Falling Back Towards the Ground
The dark, prickly beast slides forward like death on rails. With any hope of self-preservation exhausted in your mind, you let out a primal yell from a tired throat and launch yourself back into a tumbling fall, bound for the ground. The air roars around you and your teary eyes are momentarily calmed with the realization that the tunnel from whence you came is almost directly below you. Returning to the library would be better than dying though not by much, so you begin to aim yourself for the hole.
