Tash was a prowlgrin raised by Quint during his training as a squire in the Knights Academy. Quint named him "Tash" because of his distinctive tuft of hair. Naming his prowlgrin was a violation of Knights Academy regulations, which stated that prowlgrins may only be named by Knights academic-in-waiting, and they may only be given names ending with -ix. Screedius Tollinix reprimanded Quint when he caught him calling Tash by name.
