The actual war in Divinity: Dragon Commander is played out on the Strategy Map, which is an overview of the entire world you are fighting for. Each player has a turn during which he/she can make his/her moves. After every player has ended his/ her turn, resolutions will be played.
Countries on the map start off as divided between players (or AI) or as neutral zones that are fit for capturing.
Once a country has been captured, it will receive the assigned colour of its conqueror.
In single player mode, countries also belong to certain races. Each race has a particular affinity towards you, depending on your choices aboard the Raven. This may have a positive or negative impact on your campaign, such as improving or reducing the amount of resources available to you, or causing you to receive more or fewer cards to play on the battlefield.
