The Lost City was an underground city created by the warlord Kamaros. It was based around a gold mine and Kamaros drugged people with Lotus Leaf so they would work for him in the mine. He would then sell the gold to bandits. The Lost City was destroyed when Iolaus revealed that Kamaros was using people. The warlord had the entire city rigged with a series of counterweights that collapsed it.
