Carthage in A Different Flesh[]

Carthage was a large town in the Federated Commonwealths. Hairy elephant driver Prem Chand was headed to Carthage in 1782 when he stopped in Springfield. While there, he challenged Richard Trevithick's Iron Elephant to a race. Much to the chagrin of several passengers, they had to find other transportation to Carthage.
