Identity: the Sapphire Coast League is a maritime web of port cities, ship guilds, storm temples, merchant houses, pearl banks, pilot families, quarantine boards, and discreet political financiers.

Why it is wealthy: the League moves what roads cannot: grain during famine, relics in secrecy, exiles at night, salt, pearls, stormglass, foreign news, forbidden books, plague warnings, and letters no court admits receiving.

Political structure: authority is shared by port councils, ship guilds, storm priests, merchant judges, pilot families, private convoy captains, and bank houses that can ruin a noble without drawing steel.

Relationship to Valemere: the League officially respects the crown but funds multiple claimants to keep tariffs favorable. It prefers a lawful ruler, but not one strong enough to inspect every hold.
