In the fourteenth century, the Pope declared the knights of the Order of Christ and the Temple of Solomon—better known as "the Knights Templar"—to be heretics. Their lands and lives were forfeit. But when the Inquisition came to claim the riches rumored to be held in the Order's coffers, they found... nothing. Thirty is a roleplaying game where you'll take on the roles of thirty Templar Knights as they carry a secret treasure, become lost in a magical mist and try to find your way home. The story you tell together with your friends is the story of that journey. Where did they go? And what did they take with them? The answers are more dangerous than you can imagine.
