Sailor Pluto's Garnet Rod was an item owned and carried by Sailor Pluto, and it also held the Garnet Orb (Sailor Pluto's Talisman). It functioned as a key (somewhat) for the Space-Time Door.
Sailor Pluto used the Garnet Rod for Dead Scream, Abracadabra Pon, Time Stop, and Dark Dome Close. Sailor Pluto also had access to the rod in civilian form. This item also glows and moves by itself when one of the Telluns she studies nearly has her heart-snatched.
