Get My Damn Obelisk!

From Introduction:

Pharaoh is irate. A strange and mysterious howling has terrified the quarry workers, who have abandoned the effort to carve a new, prized obelisk. The new monument must be positioned before the festival, or the gods will be displeased. The players have been enlisted to retrieve the enormous chunk of rock.

The obelisk is located at a quarry up the river. It has been carved and finished, but the workers ran away before it could be loaded onto the barge and sent downstream to the Pharaoh’s temple.
