From the back of the book:
Knights and wizards have defended the Kingdom of Myth for centuries. These lands have known peace and prosperity, but soon the kingdom shall be destroyed.
The Prophets have declared that your city shall burn and Myth will fall. All those who follow your King shall die. It is INEVITABLE.
But you shall defy fate. Myth will not end while you bear arms.
You will fail, but as long as there are still stories, they will sing of you!
Inevitable is a Arthurian Western roleplaying game for 2-6 players and a GM, where your party of disastrously sad cowboy knights fail to stop the apocalypse. This 284 page book contains all the rules, character creation and the setting for your campaign, thoroughly and evocatively detailing The Barren, the lands surrounding the Kingdom of Myth.
Good luck failing to save the world!
