If a rule exists called “Trade”, then reword it to the following; otherwise create it, with the following text:

As a Seasonal Action, a Settler may Trade, which is an atomic action with the following steps:

* Move one or more items in their Stockpile to another Settler’s Stockpile
* Move a number of items from that other Settler’s Stockpile into their own Stockpile (where that number is within 2 of the number of items in the previous step, and above zero)
* If either of these Settlers does not have the other’s name in their Alliance, then select one random item from each of the two moved groups of items, and remove it from the Stockpile that it is in

Trading may only be performed by a Settler if they can indicate a blog post or comment made since the most recent Production of Resources where the other Settler whose Stockpile would be altered has explicitly agreed to this, specifying the items traded.

To the rule “The Gift of the Isle”, add:-

If an action is defined as Seasonal, then each Settler may only perform it if they have not already done so since the most recent Production of Resources action.
