Konstantine
Konstantine was Roz Forrester's Adjudicator trainer. (PROSE: The Death of Art) Konstantine left a deep impression on the young Roz, leading to her sometimes vividly remembering his words many years later during her travels with the Seventh Doctor. (PROSE: The Also People, GodEngine, The Death of Art)
To teach her how tedious medium-level Overcity work was, he said she had violated dress-code rules and punished her with a three month detail on the fraudster watch. After arresting Swami Rhan-Te-Goth for fraud and five counts of access to banned literature, Konstantine tried to destroy the datachips where it was stored. He swore that the Prinn chip burnt green, the Von Juntz red, and the Lovecraft one not at all. (PROSE: The Death of Art)
