Harley, also known as Herlie, is a city in Expel. It is a port town of the Krosse Kingdom, and thus, it's located in the easternmost part of the continent, beyond the Symbologist town of Marze. This city connects the kingdoms of Krosse and Lacuer.
Claude C. Kenny and Rena Lanford reach Harley after the disaster on Kurik halted them from reaching the Ell Kingdom, seeking to access Ell from this port area. Here, they board a ship that takes them to Hilton, on the Lacuer Kingdom. Just prior to Hero of Light's party crossing to Lacuer, rumors abound in the port city of a demon dragon plaguing the small southern mining town of Salva.
