Mantic Free Campaign Rules

Mortibris the Necromancer cursed and spat in the dust as he saw the host which awaited them. Leave it to the Elves to meddle in matters which did not concern them. With the Dwarfs and possibly the Basileans soon to be at his back, he could ill-afford further distractions here. No matter. The Elves facing him had no idea of the power he could unleash. Not even the blighted maiden at their head, whose essence he recognised readily enough… Madriga!
Edge of the Abyss is a global campaign that will see the map of Mantica change, depending upon whether good or evil triumphs on the battlefield. Throughout the summer of 2017 Mantic will be collecting the results from battles around the world, which means that you can decide the fate of Mantica. You’ll also find brand new heroes, new units, formations and more to bring your games of Kings of War to life.
