The Final Step, by Adam Smith

Dirk heard dripping, but there was no way into the chamber beyond. Cracks in the stone allowed light through, and a breeze was evidence that a room existed. The witch doctor told him this quest was pointless, but did block his way. He stumbled, tripping on a long white bone. Lowering the torch, he realized the entire floor was made up of crushed bones. It would have taken thousands of skeletons to provide enough material! The air began to smell sour and Dirk turned to flee. It was too late. Some day another intrepid adventurer would step on his bones.
