Lahun

A city in the Northern Upper Kingdom. Small. "This uninhabited remote outpost was once home to a lucrative diamond operation rumored to have been swept away, or underneath, the sands of the northern deserts."

It's surrounded by a high ring of dunes. Characters include: Walidah commissioned his court wizard to undeadify the soldiers. Dufduf visited here and helped Walidah build the electric machine that, perhaps, made golems out of dwarves so as to work them tirelessly?
 * Dinnerbot,a construct shaped like a trashcan on a perpetual loop
 * Two flesh golems killed in the wrecked wizard's lair.
 * Statue of Elven Pharaoh Walidah, known for his greed, ruled about 500 years ago
 * Bes statue holds a statuette of crocodile demigod Yatooma, known for his love of poetry. Recite a poem to him an see undead within 500 feet for 10 minutes.

Pots of dirt and water in the mine, surrounded by crushed onyx, are the evidence of Dufduf's early undeadifying efforts.

After reciting the poem, Hapu uses his newfound undead vision to examine the dune. There are hundreds of skeletons, and though some seem to be slowly burrowing about, there is no organized activity. Undead vision wears off after 10 minutes.

The party breaks into the adamantium safe with the explosives after a failed attempt with acid. They find seven various diamonds worth 5,000 gp each, plus two burned by acid worth 50 each.

They explore the elf quarters outside the dune, find an empty jewelery box, play some croquet.

Upon the party deciding to leave, the "stepping stones" in the river near the bridge turn out to have been the skulls of skeleton troopers. They rise out brandishing fearsome but rusted swords and armor. The party makes quick work of them with a fireball and a turning. 10 skellies run eastward into the distance. The rest get crunched.
