The Stygian Art represents a method formulated by the Dark Side Adept Cronal during the era of the Galactic Civil War. Subsequent to his unsuccessful campaign targeting the New Republic, Cronal completely adopted mechu-deru, a Sith ability enabling manipulation of mechanical constructs via the Force. Through this action, the Dark Side Adept merged mechu-deru with Sith alchemy, thereby establishing his unique creative process known as the Stygian Art. While living on the planet Trailia, Cronal dedicated several years to conducting experiments utilizing the Stygian Art on the local population. A collection of technobeasts were among the entities resulting from these experiments.
