thellësia

Thellësia is a fictional realm described in fantasy literature and tabletop role-playing sources. It consists of a coastal peninsula and a surrounding archipelago, with diverse landscapes including rugged coastlines, river valleys, and volcanic highlands. The realm is organized as a federation of semi-autonomous city-states with a strong maritime orientation.

The origin of the name is uncertain; within its canon, Thellësia is sometimes linked to ancient Thellari glossaries, but scholars largely treat it as a toponym created to evoke horizon and sea.

Geography includes the Dusk Range inland hills, the Silver Strait to the west, and the Ember Woods inland. Major urban centers are Lyrion (capital), Vanceport, and Mirrhen. The climate is temperate maritime with microclimates near volcanic zones.

Thellësia's historical narrative centers on seafaring clans founding port-city-states and later forming the Grand Council to coordinate defense and trade. The realm experienced a long era of commerce and cultural exchange, followed by periods of reform and external pressure.

The Grand Council oversees international affairs and defense, while city-states maintain local courts and councils. The Synod of Tides serves as a religious and cultural advisory body.

Thellësia's demographics and culture feature a majority language of Thellesh, with diverse dialects and immigrant enclaves. Religious life centers on the Thelean pantheon. Cultural life emphasizes seafaring lore, basalt architecture, and festivals such as the Night of the Twin Moons.

The economy hinges on maritime trade, fisheries, salt works, timber, and glass from volcanic sands. Notable sites include the Hall of Echoes in Mirrhen, the Glass Gate of Lyrion, and Moonharbor Lighthouse.
