There's a spirit, a tricky nuisance of a spirit, known for stealing the souls of the recently deceased. If left unmonitored, a corpse will attract the attention of what is known as a Cat Sidhe, which is a pesky thieving feline that will sneak into the room within which the corpse is kept and it will steal the soul from the corpse before its burial, denying the spirit rest and condemning it to roam aimlessly indefinitely.
However, this feline can be appeased and persuaded into stealing a soul for a different purpose. This piece will draw a Cat Sidhe to you and you can instruct it to visit the grave of your loved one where it will conjure their soul and guide it back to you. As long as this piece remains in your possession, the feline will live among you and with it the soul of your loved one.
The clasp on this pin is broken, which is why the price is lowered, but you also do not need to carry the cat around with you to benefit from its power.
