"Oh-whooooooahhhh" you exclaim as you stumble in the darkness, missing that first step and catching the edge of the second with the heel of your boot. How were you supposed to know that the den dropped off a few steps. The darkness surrounding you as you fall quickly and hard into something hard at the center of the den.
Your poor head collides with it as you were unable to fall gracefully. You tumble onto your back onto the carpeted den floor and quickly lose consciousness.
