From the website:
"In Chessboard Heroism you are a hero or heroine, trying to do heroic things before wars break out and your career options are reduced to boring military service. You long to solve real quests: saving people who need rescuing, finding lost magical items, fighting wild monsters, etc. But time is running out! Cards detailing quests cover a chessboard's squares. Solve the quests faster than your opponents while cooperatively maintaining the political stalemate or the game ends! And watch out for the randomly wandering dragon!"
