Devlin Stone's Military Material Redemption Program transformed the Inner Sphere, retooling BattleMech production lines for civilian output and boosting state economies. Companies that had made their names building machines of destruction now found themselves turning more towards peaceful IndustrialMech manufacture. Downsized and heavily regulated by Stone's policies, Irian Technologies was an exemplary model of the Republic's new paradigm. But IrTech has kept a secret through the long decades of peace: a fully functional Marauder II production line hidden away from the Republic's auditors and enforcers. In late 3133, however, that secret got out. With the Republic already torn by factional strife, the revelation of IrTech's deception has everyone scrambling to win the prize. Who will emerge victorious from this all-out faction war? Dark Age Turning Points: Irian uses Chaos Campaign rules and gives players the option of fighting individual battles, following a campaign arc, inserting it into their own campaigns and even creating their own scenarios with optional rules to give their games an Irian flavor. The ebook includes a detailed map of the world of Irian, a run down of the forces involved in the conflict, and several tracks that players can use to run simple lance-on-lance battles, or stage up to a world-wide invasion. Only the players' imaginations are the limits.
