There are 12 Kingdoms that you can choose from to be your Home. "And I'm the King, right?" Good one! No, you start out as the Leader of one unit of Melee Troops - 8 figures.
From there the King - not you, not yet - decides who's Going to War. Once that's established you move into the opposing country or maybe they move into your country if they declared war on you.
All battles are fought in the country until one side or the other surrenders and is annexed.
"When am I the King?"
All in due time, IF you do well. More to come.
