The Thirty Years’ War has been reforged in brass and steam. Ars Mechanica is a 70‑page field manual for Se7en Sagas, featuring sanctified Machina, battlefield doctrines, solo play protocols, and printable STL files so you can march your own constructs into war.
Whether you are a pilot chained to a walking cathedral of the Catholic League, a daring Strider ace of the Protestant Union, or a ghost‑banner mercenary carving your own creed, Ars Mechanica puts you in the cradle of a living war machine.
This is more than a supplement. It is a complete experience, blending lore, narrative mechanics, faction‑driven combat doctrines, and fully printable models to bring the Iron March to your table.
Open the cradle. Begin the war.
