In the absense of light, there can only be dark.

What becomes of man when only dark exists?

     The last gleam of light narrowed and glimmered away, and with it, hope.  Darkness filled the parameters of the cold chamber, extending to every corner and filling the void within.  In the absence of this light, only dark could exist.  A click and a clank of a lock, and the darkness finalized the annexation of its quarry; without hesitation, without prejudice, and without concern. Defenseless, dependent, and designed with an inner flaw, the light soon perished, and only dark could grow.

     "Help!" cried a young man.  "I'm still in here!  Somebody, I'm trapped."
