Were he had disappeared.....

She was sure this was where he had disappeared, as it was the last place she saw him.  They had been playing tag in the foggy forest surrounding their house.  She searches the woods they were playing in.  However she finds no trace of her beloved brother.  She circles back to the opening where he had vanished.  When she returns she notices a manhole which previously was not there.  She investigates the opening.  When she looks into the manhole she sees a ladder, but nothing else and hears nothing.   She suspects that her brother is down there.  She climbs down the slightly slim-coated ladder into the dark, dank hole.  She carefully steps off the ladder into shallow cold water.  As her eyes adjust to the darkness she slowly senses her surroundings.  She can make out the shape of a grand tunnel extending in front of and behind the ladder.  After a moment, she walks away from the ladder further into the tunnel using the wall as a guide.  As she walks she hears a distant low whimpering, whether it was her brothers or not she did not know.
