Editing Mementos (section)

== Form and Function ==
A memento's power can only be used if the ghost wills it. They may lend their strength to many, or only one specific person. Because of this, it is extremely unlikely for a stolen memento to have any magic. If a memento breaks, the ghost is released, but the ghost can choose to leave at any time. Some mementos become empty when their keepers accomplish a specific goal, and some stay occupied for generations and become family heirlooms. Occasionally, mementos become empty rather suddenly, never to awaken again, with an unclear cause. Only mediums can tell if a memento is occupied or not.

Mementos can be literally anything. If you pray hard enough and are persuasive enough, even a ghost you've never met may come to occupy an object you own. That said, all throughout Enchiron--though particularly in Sayil--it is common practice for the ill and elderly to craft mementos out of trinkets and small items to bestow upon their most beloved friends and family. The gifted mementos may never be occupied, but they serve as a reminder that the deceased will always be with you.
