A loose confederation of coastal kingdoms bound by trade, ritual, and the shared faith of . The Tidecrown Coastlands stretch along contested harbors and river mouths where have built lighthouse cities, trade ports, and farming settlements. Each kingdom maintains its own rule, but all defer to the authority of The Lantern Orthodoxy in matters of faith, cartography, and the sacred boundaries that separate the living world from the realm beyond the True Horizon. The confederation takes its name from the tidal cycles that govern its calendar——and from the crown of foam that marks the line where sea meets sky at dusk. It is a realm of careful remembrance, where names are inscribed in ledgers and maps are treated as sacred documents. Yet beneath this order lies a fracturing faith: the forbidden Roadbound Heresy spreads quietly through harbors and villages, claiming that places like are meant to be sought rather than sealed away.
Notable features
The Tidecrown Coastlands is defined by its vast network of lighthouses—blue-white lanterns burning at every headland, harbor, and river mouth—maintained by the priests of The Lantern Orthodoxy. Its cartographers are legendary, though the finest maps are locked away in sealed vaults and private archives. The confederation's coast is dotted with Grand Lantern Chapels where the dead are remembered in ritual and ink, their names inscribed in ledgers that may outlive kingdoms. Trade cities like Greyharbor serve as hubs of exchange and rumor, where sailors speak of islands that move and maps that shift when unobserved. The interior holds farming valleys and contested frontiers where older powers linger, but the heart of the confederation beats at the sea's edge, where the horizon remains both boundary and mystery.
Secrets
The Tidecrown Coastlands's deepest secret lies in what it actively forgets. The Lantern Orthodoxy maintains a hidden apparatus called the Black Wick Office, where forbidden artifacts and memory-maps are studied in secret vaults beneath and other sealed chambers. High Lantern Selovar Maen knows that is not merely a legend but a living presence drawing closer, and that the confederation's careful maps may be more than navigation—they may be wards. Most dangerous of all: during the hidden thirteenth month of Stillmere, the boundary between the confederation's mapped world and the unmapped realm grows thin. When aligns with this forgotten season, new streets appear in ancient towns, doors open to impossible passages, and the confederation briefly remembers lives it never lived. The official priesthood has spent centuries preventing anyone from completing the knowledge that would fully reopen the threshold to .

His daughter continues to haunt the confederation's archives, seeking maps her father left behind. unfolds entirely within the confederation's borders, particularly in the coastal town of Greyharbor, where the boundary between worlds grows dangerously thin. The heretical Roadbound faith spreads quietly through the confederation's harbors and villages, contradicting the Orthodoxy's teachings and threatening the careful structures that The Lantern Orthodoxy has built to keep the moving city sealed away. At the heart of all these threads lies , a relic that may unlock or shatter the confederation itself.
