Please generate a brief description of a spooky hallway with an oil stain, arch, oil reservoir, and lamp.

The remains of an oil lamp hang from the low, square rafters in the hall. A dark spot beneath the dust on the floor proves to be a large oil stain, and shards of glass against the walls seem to be from the oil reservoir. A small arch leads off to the east, lit by dim but harsh daylight.
