The frozen halls and ancient archives of the Targa Plateau are watched over by more than just lumbering Guardians and robotic Custodians. As the Library awakens, and the systems blink back to life, the Prometheon Defenders emerge from their ancient slumber to stalk the halls once more, eradicating intruders and setting out on sinister missions by order of the Archive Intelligence. Armed with the arcane Prometheus Staff, these four-armed robotic predators tower over their foes, sweeping aside all opposition up close while firing deadly energy blasts to disintegrate those that try to flee. Protectors of the Library, the Prometheon Defenders are a robotic nightmare of cold calculation and ruthless perfection.

This Mission Pack introduces the Prometheon Defenders of the Targa Plateau. With 4 new Missions that form a short story campaign, a new Objective Room Map Tile, a host of new cards including Threats, Artifacts, Enemy Traits, Darkness, and more, as well as the Enemy Record Sheet, Rules, and 6 Large Prometheon Defender models, this Mission Pack is an exciting addition to the Targa Plateau and your games of Shadows of Brimstone.
