Fortunata

Fortunata was a traitorous healer fox. She was originally hired by Lord Verdauga Greeneyes to heal him of his illness. However, she secretly agreed to poison him on behalf of his daughter, Tsarmina.

Once Verdauga was dead and Tsarmina firmly in charge, Fortunata received a high rank in her army. This, however, was exploited by the Corim, who sent the Mask, in disguise as a fox (Patchcoat), to make Fortunata assume that the two hedgehogs Ferdy and Coggs had escaped from the prison of Kotir. Fortunata masqueraded as "Besomtail" during this, but was eventually killed by Lady Amber and her squirrel archers.
