Rhuen is Spectra Vondergeist's pet ferret. In Spectra's diary, she is stated to be the Ghostly Gossip's closest confidante.
Rhuen's fur color starts out as a dark purple at the top of her body, but slowly fades to transparent shade due to her ghostly status. She also wears a little dark purple bow in front of her left ear.

- The word ferret is derived from the Latin word "ferritus" which means little thief.
