Produce a detailed written description of a spooky scene inside a tunnel with footprints and bones.

The fossilized skeleton of a large, winged beast is embedded into one of the rocky walls in this long, mostly unadorned tunnel. Though its left wing is missing entirely, the sheer size of the bones tells of the creature's former glory. A cluster of footprints overlap one another in the sooty dust beneath the single lantern that hangs from the ceiling, a visible indicator of the high traffic this area must see.
