High Adventure in the Steam Age
Chat d'argent (Cait Sith)
Euphemios is a cait sith, a faerie cat [ Memoirs of Auberon of Faerie , p. 57]; in France they are known as chat d’argent, mandragot or matagot and often serve as familiars to powerful sorcerers. He is ancient and has been friends with Penneg for a very long time. The two enjoy a lively correspondence, always cyphered and magically encoded.
