Human: Write a description of a where you are in a spooky scene outside town with a well and a plank. Assistant: 
Only a thin plank of green, worm-eaten wood lies between you and the abyss of the great well, its stone shaft plunging into darkness far below. A faint rustling sound echoes up from the pit, like leathery wings preparing to take flight, but nothing moves in the shadows. The plank runs from west to east, touching on either rim of the well.
