Trailian

Trailian is a fictional planet and setting used in speculative fiction, role-playing games, and related media. It centers on the world Trailian in the eponymous system, notable for its ocean-dominated geography and a network of coastal city-states that engage in trade, diplomacy, and occasional conflict.

Geography and environment: About 70 percent of the surface is ocean. Archipelagos encircle a continental core; the equatorial belt is warm and storm-prone, while temperate regions host rainforests and mangroves. The atmosphere is breathable, and the biosphere includes bioluminescent marine life that shapes technology and culture.

Inhabitants and culture: The primary sapient populations are the Trelani, a seafaring humanoid people, and the Velori, a merchant-oriented species with advanced trade networks. A smaller human diaspora maintains coastal settlements. Societies emphasize maritime craft, navigation lore, and a tradition of oral storytelling that preserves history and law.

History and politics: Ancients explored the archipelago and formed city-states. The Trailian Concord arose as a loose federation to mediate disputes and coordinate large projects. Key tensions involve resource rights in reefs and vents, environmental protection, and piracy along major routes.

Economy and technology: The economy centers on fisheries, seabed resources, and intercity trade. Technologies blend hydromechanics with bioluminescent materials for lighting, signaling, and medical uses. Cultural production includes music and art inspired by the sea.

In fiction and media: Trailian appears in novels, tabletop campaigns, and a video game prototype, with expansions detailing ecology, politics, and mythic traditions.
