Hall of Infinite Doors

You squeeze your face into the small opening and shout out into the seemingly open space beyound only to find the silence swallows your meager voice almost instantly;no echoes as expected and no replies...only the slow movement of the lead portal moving on it own.The smell has become fume,and you struggle to breathe without panting.You know the odour to be sulfur,and you have the feeling this is no place for you to be.Still curiosity beckons your stronger self,and you peer into the now opened doorway.
Inside is a cavernous room that seems to be the definitions of darkness complete;onyx marble floors stretch forth into the forever of the minds' eyes' sights and you are finding it harder to clearly think...Thus explaining your entering this awful place without another moments hesitation.As any one might expect,the door closes immediately and you are left to the darkness of this hidden ravine.You wait long moments for your eyes to adjust,only to realize there is absolutely no amount of light present.You begin to feel the gnawing teeth of panic in your mind;your heart threatens to come out of your chest,and GOD DAMN that smell!!
