Please generate a brief description of a spooky scene inside a tunnel tower with blocks, mortar, rodents, and riverstone.

The hands of time have been hard at work in this section of the tunnel several of the large stones lining the walls have become loose and tumbled to the floor. Small rodents can be heard scurrying in the darkness, perhaps the only creatures capable of thriving in this underground habitat. The fallen blocks of riverstone and crumbling mortar serve as a reminder that even the strongest of constructions is no match for the march of time.
