TPThe Lantern Ports
Overview
The Lantern Ports are a broad chain of coastal cities, estuary towns, and marsh villages linked by ferries and old causeways. Their harbors prosper on sea trade and on the unusual traffic drawn by unstable portals. Each port keeps its own customs, yet all depend on shared signals when a gateway misfires. Void Warriors are quietly retained to protect wealthy districts and contain breaches, while ordinary residents watch them with wary respect.
Cultures
Harborborn traditions prize mutual aid, practical seamanship, and public lantern festivals.
Portalward communities value discretion and treat unexplained absences with wary courtesy.
Inland marshfolk preserve seasonal rites tied to floods, reeds, and fishing.

History and secrets
The Lantern Ports grew from fishing villages into a linked coastal region after unstable portals began appearing near its harbors. Trade brought wealth, migrants, and strange goods, but repeated accidents taught the ports to cooperate. Their councils now share navigation rules and emergency signals while competing for commerce. Void Warriors are hired as discreet portal guards, yet their abilities remain a source of fascination and fear.
