Add a new bullet point to the first list in the rule The Cities and the Sea, bolding the word Lucre:

* An amount of Lucre, defaulting to zero.

Add a new subrule to the rule Resources, called Lucre:

A City’s Lucre is a representation of its overall wealth. Whenever a City moves a Resource from the Manifest of their own Boat to a Warehouse owned by another City they increase their Lucre by 1, plus 1 if it is a Produced Resource. Whenever a City moves a Resource from the Warehouse of a City other than themselves to the Manifest of their Boat they increase the Lucre of the City whose Warehouse they moved the Resource from by 1, plus 1 if it is a Produced Resource.

In the rule Cargo change the word ‘good’ to ‘Resource’.

Add a new rule to the ruleset, called Treasure Fleet:

A City’s Trading Heft is calculated as follows:
* A starting value of 0
* +1 for each Lucre held by that City
* +1 for every three Resources held in Warehouses or Manifests by that City
* +2 for each Boat owned by that City

If a single City has the highest Trading Heft on or after 4 July 2025 then no further dynastic actions may be taken, no initiated Timed Actions may resolve, and that City has achieved Victory.
