trianoni

Trianoni is a fictional geographic and cultural concept used in speculative fiction and tabletop role-playing games to describe a triadic borderland or archipelago.

The name combines the prefix tri-, meaning three, with an -anoni suffix invented for world-building; there is no historical language basis for the term outside its fictional use.

In most depictions, Trianoni comprises three principal islands radiating from a central lagoon, connected by shallow channels and small ferry lines. Its climate is temperate, with sea breezes and wet winters, supporting a varied coastal ecosystem.

Legends say three maritime polities—Aeron, Brise, and Corin—formed Trianoni through centuries of trade and treaty. A Tri-Council historically governed the region, balancing interests among the three communities and providing a framework for dispute resolution and shared infrastructure.

The three communities maintain distinct customs and languages yet share a common lingua franca used in administration. Architecture blends three stylistic traditions; cuisine reflects coastal and market-town influences. An annual Tri-Unity festival celebrates cooperation and cultural exchange.

The economy centers on sustainable fishing, craftwork, shipbuilding, and ecotourism. Transport relies on ferries linking the islands and a small airstrip on the central island. Conservation areas are commonly highlighted in planning and tourism materials.

Trianoni serves as a setting to explore diplomacy, identity, and environmental issues, and appears in novels, games, and world-building guides as a versatile backdrop for storytelling.
