Instrument
The Carthis Commercial Charter
The Grant Carthis Cannot Amend
The Velyrian grant under which Carthis contracts, adjudicates claims, and carries commercial obligations beyond its ports without acquiring sovereignty or amendment power.
The Carthis Commercial Charter is the grant under which Carthis conducts commerce in a name larger than any one quay. It allows the moon to contract, accept obligations, bring claims, collect tariffs, and maintain charter courts whose records survive the departure of cargo and parties. What began as an instrument for a largely agricultural holding now carries the traffic of an inhabited mercantile world. The charter makes Carthan commerce portable. It does not make Carthis sovereign.
Velyr granted the charter about ten centuries ago, early in the High Seat’s rule, and remains the authority behind it. House Aurethane holds the original under its written title, the Charter of Carthan Commerce, produces it when a provision is challenged, and answers for the meaning Velyr gives the instrument. The house did not compose the grant, cannot alter it, and does not govern Carthan ports. Carthis works under the charter, but cannot amend it or withdraw from it. The distinction is exact: custody gives Aurethane a recognized voice in interpretation, while daily government remains with Carthan institutions.
The Scales administers that daily work from Cadran Exchange. Its bonded quays and counting houses govern permits, charter courts, contracts, tariffs, and commercial arbitration, with the Arbiter declaring when a dispute is finished. Cargo may leave Marnis Quay, change ownership beyond Carthis, and still answer to a bond or judgment preserved at Cadran. The instrument gives those proceedings continuity across ports. It does not place every transaction under a Velyrian officer, nor does it allow Aurethane to assign a berth, set a local fee, or direct a Carthan court.
Carthis may act under its collective charter name. A contract made in that name can bind the commercial body rather than a single warehouse or quay, and a claim entered beneath it can be heard beyond the district where the quarrel began. The Carthan charter seal proves that commercial authority has been engaged. It is not the sovereign seal of Velyr. It cannot revise obligations reserved to Velyr, turn a local judgment into imperial law, or give the Scales powers the charter never granted.
Aurethane’s interpretations matter because commerce depends on what other courts will recognize. For three centuries, Carthan factors have learned that a reading entered beside the original can redirect trade as completely as a closed quay. A disputed provision therefore travels upward without carrying the whole port with it. The Scales states the matter through its record; Aurethane produces the charter and answers for Velyr’s understanding. The delay required to obtain that answer can preserve an obligation, spoil an advantage, or make settlement preferable before any ruling arrives.
Carthan self-government is dated from practice rather than from the grant itself. The Scales names its beginning as the first session in which one quay lost to another and paid without appealing to Velyr. The charter was eleven years old. That remembrance does not claim that Carthis created its own authority. It marks the moment Carthan institutions proved they could use delegated authority against a local interest and have the result obeyed.
The charter’s deepest limit remains in the archive with it. The Chairs or the High Seat may withdraw the grant. Carthis cannot prevent that act through amendment, and Aurethane cannot preserve the instrument against the power from which it came. No proposal to revoke it has reached a recorded sitting, and no surviving draft begins the attempt. The unused power nevertheless remains operative enough to shape every reminder that Carthis works beneath a Velyrian grant.
The charter is tested whenever commercial competence approaches political independence. Carthis can govern crowded ports, enforce contracts, and make a seal respected far beyond Marnis Quay without acquiring the authority to redefine its external obligations. Velyr, for its part, can preserve a dormant right of withdrawal without proving how either imperial body would exercise it. The instrument endures because both sides profit from the distinction. Carthis receives reach without sovereignty; Velyr retains authority without administering the commerce that makes the grant valuable.
