Linkstones take the physical forms of precious gemstones which a stoneholder keeps on their person at all times. Every Cycle member has a stone associated with them that represents their personality. The current stoneholder may communicate with a previous stoneholder’s spirit (if their stones match).
A much more negative effect, however, is that the current stoneholder inherits all of the previous stoneholders’ permanent physical injuries — usually to a much lesser extent, but due to the strange nature of Linkstones, there is a chance that such an injury could worsen for the inheritor.
