You are a monarch, like your parents before you, a ruler of a small pleasant kingdom of rivers and evergreens. Unlike your parents, however, you have hopes and dreams! You want a bigger and more pleasant kingdom, with more rivers and a wider variety of trees. You want a Dominion! You will bring civilization to these people, uniting them under your banner.
The world is big and your kingdom small. Small when compared to the world, that is; it's moderate-sized when compared to other kingdoms. But in a big world like this one - big when compared to smaller worlds anyway, if such things exist; it's moderate-sized when compared to worlds of roughly the same size, and a little small when compared to worlds just a little larger - well, to make a long story short - short when compared to longer stories anyway - it is time to stretch your borders.
You've heard of far-off places - exotic countries, where they have pancakes but not waffles, where the people wear the wrong number of shirts, and don't even have a word for the look two people give each other when they each hope that the other will do something that they both want done but which neither of them wants to do. It is to these lands that you now turn your gaze.
Dominion Hinterlands Expansion is an expansion for Dominion, and must be played with either Dominion or Dominion Intrigue (or both), and cannot be played on its own.
