Binders are a type of guardian that have a higher degree of control over Spirit and can bend ordinary ethereo-spatial limits. Because they are classified as Guardian, their aura is orange. A binder's specific ability is just as the name suggests. By carving the name of a spirit onto their body, a binder is able to hold control over the spirit. They are able to set limits as to how far the spirit can drift, and, by simply calling out the name, they can summon any one of their boundlings to them. If thrown as a spirit spool might be, the binder's Spirit carry with them the power, determination, and energy that their master puts into them.
