They were tough times, the days when swords and magic still ruled the world. A long, destructive war had ended, and the entire continent had been unified. Before the empire's subjects had even come to know peace, however, their great emperor fell victim to disease, having never declared a successor...

We must not return to that war-torn world! Thankfully you are an influential figure in the empire. Quickly lay claim to the throne and ensure the rock-solid unity and peace of the continent.

Garner support from all over the country, clash with rival candidates and depend on your special skill!

Heart of Crown is a deck-building card game. Each player starts with the same deck, strengthens that deck with strategic cards, and finally one player will declare victory by throning the princess he controls. Each player's deck starts with seven "Rural" territory cards and three "Apprentice Handmaid" succession cards (an unreliable subject). Using the currency (coins) generated by your "Rural" territory cards, you incorporate cards from the market into your deck according to your own strategy.
