At some point following the Battle of Mindor in the Galactic Civil War, a Dark Side Adept by the name of Cronal engineered a collection of technobeasts on the planet of Trailia. Cronal, while living on Trailia, dedicated years to conducting experiments on the native inhabitants, employing his Stygian Art, a method that combined Sith alchemy with the power of mechu-deru. These experiments led to the transformation of several Trailians into mutants known as technobeasts. Eventually, Cronal departed Trailia with the best of his creations, seeking shelter on Corsuscant. Subsequently, Cronal was compelled to escape for his safety when Irek Ismaren, a subject of his cybernetic augmentations, became erratic, leading him to abandon the Trailian technobeasts to guarantee his own survival.
