 The strategy phase exists to set up the tactical battles, which take place on hex-grid battlefields, with each hex representing a terrain type, some of which also show seasonal changes.Allied troops in districts adjoining the one where a battle is taking place can be asked to join the fray as well.Commanders place their armies on the field depending on which district they have entered from (and the navy can be used to transport troops into battle as well if there is coastal access to the district).
