The first city known to archaeology, called Roghelao, was built in OTL Mongolia, about 600,000 years ago. Archaeologists have found evidence of an early caste system and iconography of the Laghic religious beliefs. Herding and craftwork made up the main activities of the city. Domesticated animals such as gharotas (tricorns, a descendant of the triceratops) and logois (a descendant of the brontosaur) were herded for meat; they practiced the arts of scale-carvings, leatherwork, and gold/silversmithing.
