Produce a detailed written description of a spooky wilderness scene with an oak tree and a shield-sized wooden object.
assistant
An ancient black oak, bearing a hide of wrinkled grey bark, squats amidst the scattered cobblestones which once formed a path through these woods. Clasped within its sprawling, exposed roots is a shield-sized wooden object, its surface nearly covered in a mass of damp fungus. Something moves in the leafy branches overhead, its form masked in shadow.
