Return to Clockwork City

"Millennia ago, the tinkerer god Sotha Sil built himself a hidden sanctuary, from which to shape his vision of the future. He called it the Clockwork City, and it was there that he died, when a fellow god betrayed and murdered him. What secrets died with him? What was he building in those gleaming halls? In the centuries since, no mortal has entered the city. Until now."
