Pistachio is the first member of Three4one to make an appearance in the comic, and the first character to be seen in Crow Cillers. She is a former member of The Order of the Crow and escaped from the cult in the first panel of the comic, which has become a frequently used and referenced moment persistently throughout the series.
Early in the series she was seen often with the mysterious Howdy Crittler doll.
