Riddleport

Riddleport is the third-largest city in Varisia and is a haven for pirates and sea-faring brigands, who find themselves far to the north of the Arch of Aroden. Teeming with criminals and rogues of all kinds, Riddleport is full of potential danger and hard-to-avoid intrigue. Also known as the City of Cyphers, Riddleport takes its name from the Cyphergate, a giant stone arch spanning the natural cove around which the city is built. It is covered on both sides with ancient Thassilonian symbols, although their exact meaning is unknown.
