Queen Berúthiel’s cats is one of only two references in The Lord of the Rings that had no pre-written backstory or existence outside of the book, according to a letter that Tolkien wrote in 1956.

A scimitar is a sword with a curved blade. Scimitars were used in the Middle East as slashing weapons, often wielded by warriors on horseback. Scimitars appear on the coat of arms of Saudi Arabia.
