Cipher

Cipher is Tess O'Conner's familiar, usually taking the form of a red fox. Keegan O'Conner has learned to summon him as her own familiar using Tess' spellbook now that Tess is dead.

Cipher does not like Keegan very much, since she's a little rough with him and does not understand animals very well. He likes to steal objects from people he does not like and hide them around, and make a mess of their things.
