Please generate a brief description of a spooky hallway with a barrel and a lid.
assistant
Hollow metal columns rise from the platformed floor to the domed ceiling, forming a makeshift skeletal structure that holds up the roof of sliding steel sheets. Walls rise up on either side of the hallway, stopping short of the concave dome high above. A large metal barrel is built into the floor, capped securely with a slightly domed lid and stained black in patches.
