The cave of time
As you enter the cave, you see a flickering light ahead and you smell smoke. You make your way along a winding passageway and enter a large chamber. Fires rise out of earthen vessels.
Several short, stocky people with straight black hair and primitive faces are painting pictures on the walls of the cave. They are dressed in animal skins. In a corner of the cave are beds of straw.
You stand, slightly afraid, as the cave people drop their work and run over and stare at you in disbelief. The largest man is carrying a long vine. He steps forward as though he might seize you and tie you up.
