A Barrow-wight is a portion of a strong spirit, buried with their belongings, or at a place of personal significance. The mythic portion may stay associated with the remains for a time, but certain types of burial lend themselves to dissociation from the departed, such as forest overgrowth, or simply being forgotten after a great deal of time. The mythic portion may be revered elsewhere, while the primitive animate identity remains bound to treasures. If enough of the will remains in the ghost, it's strong connection to a particular place or items may allow it to animate it's bones and manipulate the living.
