- ―Mechu-deru vitae incantation
Mechu-deru vitae was a dark side power that allowed the user to create Sithspawn called technobeasts. A Sith Lord known as Belia Darzu derived the power from mechu-deru, a technique granting absolute control over mechanical systems through the Force. Using her knowledge of mechu-deru, along with Sith alchemy, Darzu created a technovirus capable of converting the flesh of living beings into metallic parts, eventually transforming them into technobeasts. As such, the technique used to form these creatures became known as mechu-deru vitae.
