Engine Magick is the latest scientific advancement in the fantastic wonders of the Castle Falkenstein world, a seemingly improbable fusion of Science! and Magick. These devices, known as Sorcerous Engines or Sorcerous Automata or simply "Magick Engines", have the ability to draw Magickal energy from the area and create a single Magickal effect, without Harmonics or relationship to the target of the effect.
While Engine Magick is a recent development (due to the nascent presence of Thomas Olam, Futurian), it actually has its roots in the Codex Pacifica, the fabled "lost Codex" of Leonardo da Vinci. When these writing resurfaced, it allowed the Bavarian military to construct Aerocruisers, establishing them as a dominant military power in New Europa.
All magickal engines have some component of Cold Iron in their construction, due to its native ability of drawing magickal energy. Magickal Engines, unless poorly constructed, do not produce Harmonics, and may produce either a repeated spell effect, a continuous spell effect, or a single-use spell effect, as long as its engine machinery still works. While it cannot create a true perpetual motion machine (since it requires outside Magick to work), many of the effects produced by various Sorcerous Engines can maintain continuous motion and operation (i.e. the steam boiler produces movement which powers the sorcerous engine which heats the steam boiler which produces movement, etc.).
