== War ==
When diplomacy fails, war can be declared.

An empire chooses which system to attack and then the attacker and
defender proceed to combat rolls.

During combat, 'fd10+b' is rolled, where 'f' is the amount of
fleets an empire has and 'b' is all relevant bonuses. The defender
can add 10 automatically to the roll for every planet in the system.

However, the amount of fleets an empire can have is limited by the
fleet cap. The fleet cap at first is the amount of planets possessed
(note that systems above light red have more than one planet) but can
be increased by logistics fleets and planetary projects.

Each combat roll represents an entire campaign for a system, the roll
as a whole shows how well your empire performed. If the attacker wins,
they can occupy the system, gaining bonuses equal to the system's
value or exterminate a system, denying its bonus values to anyone else.
