The practice of animating an object with an existing living soul. However the binder acquires the soul, they then inscribe markings onto the target object to make it a vessel and guide the soul into it.
Once in, the vessel can be enhanced in several ways by the soul. For instance, a blade may embolden its wielder qnd make them keen of eye. A small statue may begin moving or talking. Skill Binders can better predict these effects and shape the vessel to achieve them.
The quality and permanence of the markings directly scales the stability of the binding. If unstable, then the vessel may break if the soul exerts too much power.
While often misconstrued as a relative to Hemoturgy, Soul Binding does not require the sacrifice of the bound soul’s living body. Many times, the soul bound was lost and wandering, or even a spirit who never had a body. In addition, some practitioners make great effort to recruit the soul or spirit as a willing participant. Though certainly not all.
