Chips

Aysea was a gambling city long before it was three cities, and its money still shows it. Chips are the common currency across all three territories, a survival of the old casino floors that hardened into something far more practical once the tables stopped being the point. The form endured for plain reasons: a chip lasts, it sorts and carries easily, and it reads clearly even in a crowded market, poor light, or rough handling. Struck in values of one, five, and ten, chips give the divided city a single money that needs no translating as it crosses between checkpoints, docks, shrines, and black trade. It is one of the few reasons a fractured Aysea still behaves like a single economy at all.
  Nowhere is that plainer than in Stack City, where chips are simply the medium for everything. They buy access, time, protection, silence, and survival, and they change hands faster than the truth does. People there rarely just spend chips; they turn them into other things entirely, a shipment, a body, a favor, or a future that may or may not pay off, and behind the whole arrangement the Merican Financial Institute keeps the count. Elsewhere the chip does humbler work, paying for lodging, passage, drink, and a night's gambling on the Empire Boardwalk, where a person can lose months of wages before sundown, or landing in the palm of someone who has just sold off a measure of their own Infection.
  Each territory mints its own branded chip, and the branding does more than mark origin. It signals trust and local backing, tying the coin to the identity of the power behind it. A Stack chip carries the weight of commercial dominance and broad liquidity. A Harbormarch chip carries the authority of organized labor and the systems that keep freight moving. A chip out of the Holy City of Vestige carries sacred legitimacy, the flow of pilgrims, and the communal trust that grows out of religious duty. All three are accepted everywhere, but each territory quietly rewards loyalty to its own markets, and paying with local coin at home tends to win better prices, smoother dealings, and the sense of belonging to the local order rather than merely passing through it. The result is one broad economy with three centers of gravity, where every coin holds value but the local one holds a little extra at home.
  That preference leaves room for friction. Plenty of shops balk at taking a neighbor's foreign issue at face value, some in Stack City putting more faith in northern finance than in labor credit out of the south or claims of sacred standing out of the west, and houses in Vestige and Harbormarch doing the same out of loyalty, leverage, or plain caution. Into that gap steps the Trade Union, the coast's steadiest money-changer, swapping one territory's chips for another's at a small fee across its bonded warehouses, exchange counters, market offices, and ports. Publicly the Union frames the fee as the cost of keeping regional commerce stable and the wider eastern trade network open. Quietly, some share of that margin is believed to go toward rebuilding Dominus Columbia, which gives the Union a discreet stake in nearly every cross-territory purchase in Aysea. A worker changing Harbormarch coin for Stack issue, or a pilgrim converting Vestige marks before heading north, is doing more than completing a sale. They are feeding a wider contest over who will shape the coast in the years to come.
