環

Together with the next kanji, the keywords spell “send back the ring”. First we have a jewel. Next we have the great eye of Sauron searching for the fellowship hiding under the many ceilings during their journey. The fourth and fifth primitives are the mouth of Gollum always mumbling “My preciousss”; and Pippin's scarf! Placement: the eye appears at the top similarly to how the Great Eye of Sauron is perched atop the Dark Tower.
