Bonds are a strange thing in Benteria as they come in many forms and offer a great many different gifts depending on the type and strength of the bond. All of these bonds can be deepened over time, save for the one formed by the Kikoji Siba. There are benefits to all bonds, ranging from simple energy sharing to varying forms of telepathy. In addition, the strength of the bond is tied to the emotions of the involved individuals. For example, if a couple is married for many years and one passes, the pain can be felt in the other emotionally and can also affect their physical and mental health. Similar effects have been recorded to occur in siblings, parent-child bonds and even between very close friends.
