fissiolle

Fissiolle is a fictional island and setting used in speculative fiction and tabletop world-building materials. It is described as part of the Archipelago of Orisia, located in a temperate sea to the south of the fictional mainland. The island covers roughly 18 square kilometers and features a rugged coastline of sea cliffs, several coves, and a central basalt plateau rising to a maximum height of about 420 meters.

Flora and fauna include a locally endemic pine, Pinus fissiolei (fictional), and several seabird species characteristic of small Mediterranean-style islands. The climate is temperate with dry summers and wet winters, shaping a landscape that supports scrub, pine groves, and coastal meadows.

Human settlement centers on the village Costa Ventosa, with a small harbor, a lighthouse at Cape Miraglia, and a fishing-centric economy. Tourism and small-scale quarrying are described as supplementary activities in some sources. The island’s cultural life centers on a late-summer lantern festival and a traditional sea-song repertoire, which appear in various tales and game sourcebooks.

History and usage: Fissiolle first appeared in a 1990s-era speculative guide to the Orisia archipelago and has since been featured in novels, short stories, and tabletop role-playing settings to illustrate themes of isolation, ecological change, and micro-history. It is frequently depicted with lore about a vanished trade route and a centuries-old lighthouse maintained by a small crew.
