A small trinket from their life that remains in the physical realm, but they can still interact with, and others can interact with. 

You are physically tied to this object, and cannot go more than 30 feet from it without running into an unseen barrier. When you sleep, you automatically return to the object.

You can take a bonus action to go inside the trinket willingly as if it were a demidimension, but can still be attacked in this form. If someone holds it after they have willingly returned, they can communicate telepathically with each other.

If or when the character dies, the object turns into ash.
