- Famous for fonic technology and devices, this is the birthplace of the Tartarus and Albiore. Also known for rare accessories.
- A harbor which exports goods to Sheridan. A ferry to Kimlasca also leaves from this port. -- Port Sheridan
Geographically, Sheridan is located in northeastern Radessia, yielding a nearby dock that shares its name: Port Sheridan (シェリダン港?). Sheridan is a city centered around crafting and construction, aided through the advent of fonic technology and engineering. Located in a rugged terrain, the craftwork town is as sandy as it is mechanical. It hosts a few facilities used by Class M, a trio of researchers that competes with Belkend's Class I.
Similarly to Belkend, Sheridan operates with fonic technology and is where the Albiore was built by Class M. After the protagonists secure and salvage the Albiore, as well as its pilot Ginji, from the Meggiora Highlands, they return to Sheridan so the Class M can repair the Albiore and the group can use it to rescue the residents of St. Binah before its imminent fall into the Qliphoth. Later in the story, Sheridan becomes the site of a massacre as the Oracle Knights, led by the God-General Legretta, invade, many residents losing their lives in the process.
