Add the following rule, called “Battles”, to the Dynastic Rules:

When one or more Ashen Units are in the same Territory as one or more Tribunan Units, a Battle immediately begins; whichever General or Leader performed the action that initiated the Battle should add it to the publicly tracked list of Ongoing Battles. A Battle is an event that occurs when Ashen and Tribunan Units meet. Each Ongoing Battle is tracked publicly in a list which includes the map coordinates of the Territory in which it is taking place, a list of Units participating (defaulting to every Unit in that Territory), a chronological list of applied Battle Tactics (defaulting to blank), and a Cusp (always exactly 12 hours after the Battle’s beginning). A Battle’s Cusp is the moment at which the fighting begins to wane; after the Cusp, that Battle and its participants may not be the subject of dynastic actions, and any Leader may Resolve that Battle at any time. Leaders should always Resolve a Battle within 12 hours after its Cusp if they are able to do so.

Resolving a Battle is an atomic action with the following steps:
* Select an Ongoing Battle with a Cusp that has passed.
* Mark the selected Battle as Concluding in the publicly tracked list of Ongoing Battles. If the selected Battle is already marked as Concluding, skip this and all following steps in this action.
* Apply the effects of each of the selected Battle’s listed Tactics in chronological order, including Hidden Tactics.
* For each Tribunan Unit in the Battle, roll a number of DICE6 equal to their Arms, adding together the results as follows: on a roll of 1-3, add nothing; on a roll of 4-5, add 1; on a roll of 6, add 2. The total amount added in this step is the Tribunan Total for this battle.
* In no particular order, compare the Battle’s Tribunan Total to each Ashen Unit’s Armour. For each, if the Tribunan Total is higher, reduce that Ashen Unit’s Size by the difference (to a minimum of 0).
* For each Ashen Unit in the Battle, roll a number of DICE6 equal to their Arms, adding together the results as follows: on a roll of 1-3, add nothing; on a roll of 4-5, add 1; on a roll of 6, add 2. The total amount added in this step is the Ashen Total for this battle.
* In no particular order, compare the Battle’s Ashen Total to each Tribunan Unit’s Armour. For each, if the Ashen Total is higher, reduce that Tribunan Unit’s Size by the difference (to a minimum of 0).
* Destroy all Units in the Battle with a Size of 0 or lower.
* If the Territory still has at least one Tribuban and one Ashen Unit, all Units in the Territory retreat: Tribunan Units move one Territory to the south while Ashen Units move one Territory to the north. Otherwise, the nation with Units remaining in this Territory is Victorious in this Battle.
* Make a Story Post summarizing the Battle’s events and the resulting casualties and changes to dynastic variables.
* Remove the selected Battle from the list of Ongoing Battles.
